Question 334431

{{{-5(1-5x)+5(-8x-2)=-4-8x}}} Start with the given equation.



{{{-5+25x-40x-10=-4-8x}}} Distribute.



{{{-15x-15=-4-8x}}} Combine like terms on the left side.



{{{-15x=-4-8x+15}}} Add {{{15}}} to both sides.



{{{-15x+8x=-4+15}}} Add {{{8x}}} to both sides.



{{{-7x=-4+15}}} Combine like terms on the left side.



{{{-7x=11}}} Combine like terms on the right side.



{{{x=(11)/(-7)}}} Divide both sides by {{{-7}}} to isolate {{{x}}}.



{{{x=-11/7}}} Simplify.

Answer:


So the answer is {{{x=-11/7}}} which approximates to {{{x=-1.571}}}.
