Question

How do you solve `\frac { - ( 2x + 4) } { 8} = 3`?

Answer 1

`x=-14`

Explanation:

`(-(2x + 4))/8 = 3`

`((-(2x + 4))/8) * 8= 3 *8`

`-(2x+4) = 24`

`-2x -4 = 24`
`-2x -4 +4 = 24+4`
`-2x = 28`
`(-2x)/-2 = 28/-2`
`x= -14`

Answer 2

`x = -14`

Explanation:

Step 1) Multiple each side of the equation by `8` to eliminate the fraction.
Step 2) Multiple the term in parenthesis by `-1` to remove the parenthesis
Step 3) Solve for `x` while keeping the equation balanced

`8((-(2x + 4))/8) = 3*8`

`-(2x + 4) = 24`

`-2x - 4 = 24`

`-2x - 4 + 4 = 24 + 4`

`-2x - 0 = 28`

`-2x = 28`

`-2(x/-2) = 28/-2`

`1x = -14`

`x = -14`
