-12x = 144
Distribute -4(x - 9)
Distribute 4(x - 9)
What is the first step? 4x - 6 = -12
x/-3 = -4
x - 7 = 12
x + 7 = -12
x/-5 + 9 = 16 What is the second step?
x/-5 + 9 = 16 What is the first step?
What is the second step step? 4x - 6 = -12
Subtract 9 on both sides.
19
12
4x - 36
Add 6
-12
-19
Multiply by -5 on both sides.
Divide by 4 on both sides.
-4x + 36
