Answer 1

Explicación paso a paso:

1.- 2x -7 = -3

2x= -3 + 7

2x = 4

x = 4/2

x = 2

2.- 3x + 5= -1

1 + 5 = 3x

6 = 3x

6/3 = x

3 = x

3.- 2x -8 = 10

2x = 10 + 8

2x = 18

x = 18 /2

x = 9

4.-. 5x -7 + 2x = 4x +5

5x +2x - 4x = 5+ 7

3x = 12

x = 12/3

x = 4

5.-. 5x - 2x - 4 = x + 7- 5

5x - 2x - x = 7 - 5 + 4

2x = 6

x = 6/2

x = 3
