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
