Sample Problem
What is the solution to the equation 4(x - 1) = 2x + 6?
Answer Options
(A) x = -1
(B) x = 0
(C) x = 2
(D) x = 3
(E) x = 5
View Correct Answer
(E) x = 5
On the left side of the equation, simplify the expression 4(x - 1) to get 4x - 4. This gives 4x - 4 = 2x + 6. Then add 4 to both sides of the equation to get 4x = 2x + 10. Then subtract 2x from both sides of the equation to get 2x = 10. Next, divide both sides of the equation by 2, which gives the solution x = 5.
