Answer 1

Оставляете слева действия с неизвестным а остальное переносим в правую часть и считаем вот так:
...*6+16=70
...*6=70-16
...*6=54
...=54/6=9
дальше сам по аналогии
...:6+43=50
...:6=50-43=7
...=7*6=42

Answer 2

г) ...*4 + 18 = 50 ...*6 + 16 = 70 ...

To solve this problem, we need to find the missing numbers that will make the equations true.

Let's start with the first equation: ...*4 + 18 = 50

To find the missing number, we can subtract 18 from 50 to get 32. Then, we divide 32 by 4 to get the missing number, which is 8.

So, the missing number in the first equation is 8.

Now, let's move on to the second equation: ...*6 + 16 = 70

Again, we can subtract 16 from 70 to get 54. Then, we divide 54 by 6 to get the missing number, which is 9.

Therefore, the missing number in the second equation is 9.

д) 26 + ... + :7 = 32 38 - ... + :6 = 32 ... - 35 :7 = 32 48 : 6 = 32

In order to solve these equations, we need to find the missing numbers that will make the equations true.

Let's start with the first equation: 26 + ... + :7 = 32

To find the missing number, we can subtract 26 from 32 to get 6. Then, we multiply 6 by 7 to get the missing number, which is 42.

So, the missing number in the first equation is 42.

Now, let's move on to the second equation: 38 - ... + :6 = 32

We can subtract 32 from 38 to get 6. Then, we multiply 6 by 6 to get the missing number, which is 36.

Therefore, the missing number in the second equation is 36.

For the third equation: ... - 35 :7 = 32

We can multiply 35 by 7 to get 245. Then, we subtract 245 from 32 to get -213.

The missing number in the third equation is -213.

Finally, for the last equation: 48 : 6 = 32

We can divide 48 by 6 to get 8.

Therefore, the missing number in the last equation is 8.

е) 80 - ...*... = 35 47 + ... + :... = 55 58 - ...*... = 34 63 + ...*... = 78

To solve these equations, we need to find the missing numbers that will make the equations true.

Starting with the first equation: 80 - ...*... = 35

We can subtract 35 from 80 to get 45. Then, we can find two numbers that multiply to 45. One possible solution is 5 and 9.

Therefore, the missing numbers in the first equation are 5 and 9.

Moving on to the second equation: 47 + ... + :... = 55

We can subtract 47 from 55 to get 8. Then, we can find two numbers that add up to 8. One possible solution is 3 and 5.

So, the missing numbers in the second equation are 3 and 5.

Now, let's solve the third equation: 58 - ...*... = 34

We can subtract 34 from 58 to get 24. Then, we can find two numbers that multiply to 24. One possible solution is 3 and 8.

Therefore, the missing numbers in the third equation are 3 and 8.

Lastly, for the fourth equation: 63 + ...*... = 78

We can subtract 63 from 78 to get 15. Then, we can find two numbers that multiply to 15. One possible solution is 3 and 5.

Thus, the missing numbers in the fourth equation are 3 and 5.

ж) 90 - ...*... = 18 27 - ... + :... = 20 84 + ...*... = 100 49 + ... + :... = 56

To solve these equations, we need to find the missing numbers that will make the equations true.

Let's start with the first equation: 90 - ...*... = 18

We can subtract 18 from 90 to get 72. Then, we can find two numbers that multiply to 72. One possible solution is 8 and 9.

Therefore, the missing numbers in the first equation are 8 and 9.

Moving on to the second equation: 27 - ... + :... = 20

We can subtract 20 from 27 to get 7. Then, we can divide 7 by 1 to get the missing number, which is 7.

So, the missing number in the second equation is 7.

Now, let's solve the third equation: 84 + ...*... = 100

We can subtract 84 from 100 to get 16. Then, we can find two numbers that multiply to 16. One possible solution is 4 and 4.

Thus, the missing numbers in the third equation are 4 and 4.

Finally, for the fourth equation: 49 + ... + :... = 56

We can subtract 49 from 56 to get 7. Then, we can divide 7 by 1 to get the missing number, which is 7.

Therefore, the missing number in the fourth equation is 7.
