Question

HELP ME PLEASE!!!!!!!!!!4(a+2)=8+4a

Answer 1

All real numbers are correct! Hope that helps.

Answer 2

a can be anything. There are infinite solutions.

Explanation:

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

Expand:

`4a+4*\:2=8+4a`

`4a+8=8+4a`

Subtract 8 from both sides:

`4a+8-8=8+4a-8`

`4a=4a`

Subtract 4a from both sides:

`4a-4a=4a-4a`

`0=0`

Since both sides are equal, a has infinite solutions as no matter what value it is, it will not affect the end result of
`0=0` which is true.
