Question

Solve for a

4(a + 3) = 12 + 4a
M. No solution
N. 12
0. All Real Numbers
P. 4

Answer 1

O.) All real numbers.

Explanation:

4 (a + 3) = 12 + 4a

4a + 12 = 12 + 4a

4a + 12 - 12 = 12 + 4a - 12

4a = 4a

4a/4 = 4a/4

0 = 0

All possibilities of other real number can fit into the equation. Hence, the answer is O.) All real numbers.

Answer 2

O. All Real Numbers

Explanation:

4(a+3)=12+4a

1) Distribute 4(a+3):

4a+12=12+4a

These values are exactly the same, meaning all real numbers will work!
