Answer 1

Ответ:

1) x=15-7=8

2) у= 20-10=10

3) x=17-10=7

4) у=8-4=4

Answer 2

Ответ: 1) x +7=15

x=15-7

x=8

2) 20-y=10

y=20-10

y=10

3) 10+x=17

X=17-10

x=7

4) 8-y=4

y=8-4

y=4

Answer 3

To solve each of these equations, follow these steps:

1. x + 7 = 15

To solve for x, we need to isolate x on one side of the equation. To do that, we'll subtract 7 from both sides:

x + 7 - 7 = 15 - 7

x = 8

So, the solution for this equation is x = 8.

2. 20 - y = 10

To solve for y, we need to isolate y on one side of the equation. To do that, we'll subtract 10 from both sides:

20 - y - 10 = 10 - 10

• y = 0

Now, to find y, we need to multiply both sides by -1 (to get rid of the negative sign):

-1 * (-y) = -1 * 0

y = 0

So, the solution for this equation is y = 0.

3. 10 + x = 17

To solve for x, we need to isolate x on one side of the equation. To do that, we'll subtract 10 from both sides:

10 + x - 10 = 17 - 10

x = 7

So, the solution for this equation is x = 7.

4. 8 - y = 4

To solve for y, we need to isolate y on one side of the equation. To do that, we'll subtract 8 from both sides:

8 - y - 8 = 4 - 8

• y = -4

Now, to find y, we need to multiply both sides by -1 (to get rid of the negative sign):

-1 * (-y) = -1 * (-4)

y = 4

So, the solution for this equation is y = 4.
