A)×+2=-1
B) 6 x + 12 = 54
C) 5 x - 14 = 31
D) 4 x + 28 = - 24
E) 9 x -3 = 95

Answer 1

A) x +2 = - 1

x = - 1 - 2

x = - 3

B) 6x + 12 = 54

6x = 54 - 12

6x = 42

x = 42/6

x = 7

C) 5x - 14 = 31

5x = 31 + 14

5x = 45

x = 45/5

x = 9

D) 4x + 28 = - 24

4x = - 24 - 28

4x = - 56

x = - 56/4

x = - 14

E) 9x -3 = 95

9x = 95 + 3

9x = 98

x = 98/9
