Answer:

1.) x = -3 2.) x = 4/3 3.) x = 698/77 or 9.1

Step-by-step explanation:

1.) 4 + 2x = -2

2x = -2 - 4

2x = -6

x = -3

2.) -1 (3x - 12) = 9x - 4

-(3x - 12) = 9x - 4

-3x + 12 = 9x - 4

-3x - 9x = -4 - 12

-12x = -16

x = 4/3

3.) x - 4 = 13 (6x - 54)

x - 4 = 78x - 702

x - 78x = -702 + 4

-77x = -698

x = 698/77 or 9.1
