Answer:
-4
Step-by-step explanation:
-129 = 6(7 + 7x) - 3
Distribute the 6 into the parentheses.
-129 = 42 + 42x - 3
Add like terms.
-129 = 39 +42x
Subtract 39 from both sides.
-168 = 42x
Divide 42 from both sides.
-4 = x
Answer:
x = -4
Step-by-step explanation:
6(7 + 7x) - 3 = -129
=>42 + 42x - 3 = -129
=>39 + 42x = -129
=>42x = -129 - 39
=>42x = -168
=>x = -168/42
=>x = -4
