Question

encuentra el valor de (x)
7 (x + 4) = 42
5 (x - 8) = 40
2 (x + 6) = 14
3 (x + 5) = 12

Answer 1

7 (x + 4) = 4

27x +28 = 42

7x = 42 - 28

7x = 14

x = 14/7

x = 2

5 (x - 8) = 4

5x - 40= 40

5x = 80

x = 80/5

x = 16

2 (x + 6) = 14

2x + 12 = 14

2x = 14 - 12

2x = 2

x = 2/2

x = 1

3 (x + 5) = 12

3x + 15 = 12

3x = 12 - 15

3x = -3

x = -3/3

x = -1
