Solve 4(2x + 3) - 2(4x - 1) = 5. Which strategy is most efficient, and why?
A
Divide both sides by 2 because there is a 2 in the equation.
B
Add 1 first because there is a -1 in parentheses.
C
Move all x-terms to one side first before touching parentheses.
D
Distribute on both parts first because it may cause the x-terms to cancel and quickly show whether a solution exists.
