Question

64:x=47-39. 50+x=30*5. 75-x=14*3

Answer 1

1) 47-39 = 8 значит 64 : х = 8 значит х = 64 : 8 = 8
2)30 * 5 = 150 значит 50 + х = 150 значит х = 150 - 50 = 100
3)14*3 = 42 значит 75 - х = 42 значит х = 75 - 42 = 33

Answer 2

To solve these equations, we'll perform the necessary calculations step by step:

1. 64:x = 47 - 39

To find the value of x in this equation, we need to subtract 39 from 47:

64:x = 47 - 39 64:x = 8

So, x = 8

2. 50 + x = 30 * 5

To find the value of x in this equation, we'll first calculate the right side (30 * 5) and then subtract 50 from the result:

30 * 5 = 150 50 + x = 150

Now, to isolate x, we'll subtract 50 from both sides:

x = 150 - 50 x = 100

So, x = 100

3. 75 - x = 14 * 3

To find the value of x in this equation, we'll first calculate the right side (14 * 3) and then subtract the result from 75:

14 * 3 = 42 75 - x = 42

Now, to isolate x, we'll subtract 42 from both sides:

x = 75 - 42 x = 33

So, x = 33

To summarize:

• x = 8
• x = 100
• x = 33
