Question

Solve for a. 4(a 3)=12 4a a. no solution b. all real numbers c. −3 d. −1

Answer 1

b.) 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 b.) All real numbers.

Answer 2

4(a + 3) = 12 + 4a
4a + 12 = 12 + 4a
0 = 0

Therefore, the solution to the equation is all real numbers.
