Answer 1

Ответ:

Пошаговое объяснение:

1)х+(-2)=7

x - 2 = 7

x = 7+2

x = 9

2)-6+у=3

y = 3 + 6

y = 9

3)х+2=-3

x = -3 - 2

x = -5

4)4+m=-2

m = -2 - 4

m = -6

5)x+(-4)=8

x - 4 = 8

x = 8 + 4

x = 12

6)-2+m=1

m = 1 + 2

m = 3

7)m+1=-2

m = -2 - 1

m = -3

8)9+y=4

y = 4 - 9

y = -5

9)y+(-7)=10

y - 7 = 10

y = 10 + 7

y = 17

Answer 2

1) х + (-2) = 7 + 2

To solve this equation, we can simplify the left side by combining like terms. The expression "х + (-2)" is equivalent to "х - 2".

So, the equation becomes:

х - 2 = 7 + 2

Next, we can simplify the right side by adding 7 and 2:

х - 2 = 9

To isolate the variable х, we can add 2 to both sides of the equation:

х - 2 + 2 = 9 + 2

This simplifies to:

х = 11

Therefore, the solution to the equation is х = 11.

2) х + у = 3 + 3

To solve this equation, we can combine like terms on both sides of the equation.

The equation can be rewritten as:

х + у = 6

Since there are no like terms to combine, we cannot simplify the equation further.

Therefore, the solution to the equation is х + у = 6.

3) х + 2 = -3

To solve this equation, we can isolate the variable х by subtracting 2 from both sides of the equation:

х + 2 - 2 = -3 - 2

This simplifies to:

х = -5

Therefore, the solution to the equation is х = -5.

4) 4 + m = -2

To solve this equation, we can isolate the variable m by subtracting 4 from both sides of the equation:

4 + m - 4 = -2 - 4

This simplifies to:

m = -6

Therefore, the solution to the equation is m = -6.

5) x + (-4) = 8 + 6

To solve this equation, we can simplify the left side by combining like terms. The expression "x + (-4)" is equivalent to "x - 4".

So, the equation becomes:

x - 4 = 8 + 6

Next, we can simplify the right side by adding 8 and 6:

x - 4 = 14

To isolate the variable x, we can add 4 to both sides of the equation:

x - 4 + 4 = 14 + 4

This simplifies to:

x = 18

Therefore, the solution to the equation is x = 18.

6) -2 + m = 1

To solve this equation, we can isolate the variable m by subtracting -2 from both sides of the equation:

-2 + m - (-2) = 1 - (-2)

This simplifies to:

m = 3

Therefore, the solution to the equation is m = 3.

7) m + 1 = -2

To solve this equation, we can isolate the variable m by subtracting 1 from both sides of the equation:

m + 1 - 1 = -2 - 1

This simplifies to:

m = -3

Therefore, the solution to the equation is m = -3.

8) 9 + y = 4 + 9

To solve this equation, we can simplify the left side by combining like terms. The expression "9 + y" is equivalent to "y + 9".

So, the equation becomes:

y + 9 = 4 + 9

Next, we can simplify the right side by adding 4 and 9:

y + 9 = 13

To isolate the variable y, we can subtract 9 from both sides of the equation:

y + 9 - 9 = 13 - 9

This simplifies to:

y = 4

Therefore, the solution to the equation is y = 4.
