Answer 1

                                     Solución    

A.

2 + x = -7

X = -7 - 2

X = -9

B.

x + x + 3x = -25

5x = -25

x = -25 ÷ 5

X = -5

C.

2x = 19 - 5

2x = 14

x = 15 ÷ 2

X = 7

D.

2x + 2x = -36

4x = -36

x = -36 ÷ 4

X = -9

E.

10 + x + x = 20x

10 + 2x = 20x

10 = 20x - 2x

10 = 18x

10 ÷ 18 = x

5/9 = x

X = 5/9
