Sagot :

Answer:

1.

5x = 40

5 5

x= 8

2.

8x + 5 = -91

8x = -91 - 5

8x = -96

8 8

x = -12

3.

3x + 4 = 5x - 26

3x - 5x = -26 - 4

-2x = -30

-2 -2

x = 15

4.

5x + 9 = 12 + 4x

5x - 4x = 12 - 9

x = 3

5.

4x – 17 = 3x – 12

4x - 3x = -12 + 17

x = 5

6.

2x + 2=22

2x = 22 - 2

2x = 20

2 2

x = 10

Hope it helps. And if you think I'm wrong. Please correct me. :))
