Answer 1

1: 66 2: -3

Explanation:

9+2=11

11=x/6

x=66

-21x+28=91

91-28 = -21x

63=-21x

x = -3

Answer 2

1. x=66

2. x=-3

Explanation:

1. x\6-2=9

add 2 to both sides

x\6=11

multiply both sides by 6

x=66

2. -7(3x-4)=91

distribute -7 into parenthesis

-21x+28=91

subtract 28 from both sides

-21x=63

divide both sides by -21

x=-3
