Question

Solve.
4(a+3)=12+4a
A. -3
B. -1
C. No solution
D. All real numbers

Answer 1

4 (a + 3) = 12 + 4a Use the Distributive Property
4a + 12 = 12 + 4a Subtract 4a from both sides
12 = 12

Since the equation is the same on both sides, any number will work as a. So, the answer is D. All Real Numbers.
