First solve for x

-1%28x-1%29=5 Start with the given equation.


-x%2B1=5 Distribute.


-x=5-1 Subtract 1 from both sides.


-x=4 Combine like terms on the right side.


x=%284%29%2F%28-1%29 Divide both sides by -1 to isolate x.


x=-4 Reduce.

-------------------------------------------------------
So we know that x=-4

Multiply both sides by -4 to get

-4x=%28-4%29%2A%28-4%29

-4x=16

which is the final answer
