Question

Whats the solution to x + 4 = -x - 4

Answer 1

`x=-4`

Explanation:

To find the solution, we must solve for x. We do this by getting x by itself on one side of the equals side. In this case, we can add x to each side. This will cancel out the -x on the right side.

`x+4=-x-4\\x+4+x=-x-4+x`

Combine terms and subtract -4 on each side to cancel:

`2x+4=-4\\2x=-8\\x=-4`

Therefore, the solution is
`x=-4`.
