Hi,
For this question, we first need to distribute or multiply the 4 times each component within the factor 2 - 3x.
Therefore we get:
8 - 12x = 20
Next, we need to subtract 8 from both sides of the equation to get:
-12x = 12
Now, at this point, we need to isolate for x alone by dividing by -12 on both sides of the equation to get:
FINAL ANSWER: x = -1 or Choice D
I hope that helps you out! Please let me know if you have any other questions!
Sincerely,
Andrew

4(2 - 3x) = 20
8 - 12x = 20
12x = 8 - 20
12x = -12
x = -12/12
x = -1
â´the answer is D) x = -1

What, too hard out there for a pimp?
Divide both sides by 4.
2 - 3X = 5
subtract 2 from both sides:
-3X = 3
divide both sides by 3:
X = -1.
That is all there is to it.

4(2 - 3x) = 20
8 - 12x = 20 {distribute the 4}
-12x = 12 {subtract 8 from both sides}
x = - 1 {divide both sides by - 12}
