​ −2 ​

all real numbers

no solution

​ −1 ​

Answer 1

no solution

Explanation:

Given

4(a + 2) = 8 + 4a - 2 ← distribute left side

4a + 8 = 6 + 4a ( subtract 8 from both sides )

4a = - 2 + 4a ( subtract 4a from both sides )

0 = - 2 ← not possible

This indicates the equation has no solution

Answer 2

No solution

Explanation:

4(a+2)=8+4a-2

4a+8=8+4a-2

0+8=8-2

0= -2

no solution
