Question

-7+х=13 х+(-15)=10 -6+х=5

Answer 1

X=20
x=25
x=11 
думаю так

Answer 2

1.-7+х=13
x=13+7
x+20
2.x+(-15)=10
x=10+15
x=25
3.-6+х=5
x=5+6
x=11

Answer 3

You have three equations with one variable (x). Let's solve each of them step by step:

1. -7 + x = 13

First, add 7 to both sides of the equation to isolate x:

x = 13 + 7 x = 20

So, the solution for the first equation is x = 20.

2. x + (-15) = 10

To simplify the equation, add 15 to both sides to isolate x:

x = 10 + 15 x = 25

The solution for the second equation is x = 25.

3. -6 + x = 5

Again, add 6 to both sides to isolate x:

x = 5 + 6 x = 11

So, the solution for the third equation is x = 11.

Therefore, the solutions to your three equations are:

1. x = 20
2. x = 25
3. x = 11
