Question 712010
{{{-20-(4x-1)=-15}}} Start with the given equation.



{{{-20-4x+1=-15}}} Distribute.



{{{-4x-19=-15}}} Combine like terms on the left side.



{{{-4x=-15+19}}} Add {{{19}}} to both sides.



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



{{{x=(4)/(-4)}}} Divide both sides by {{{-4}}} to isolate {{{x}}}.



{{{x=-1}}} Reduce.
