Question 211482


{{{y+20=4y-10}}} Start with the given equation.



{{{y=4y-10-20}}} Subtract {{{20}}} from both sides.



{{{y-4y=-10-20}}} Subtract {{{4y}}} from both sides.



{{{-3y=-10-20}}} Combine like terms on the left side.



{{{-3y=-30}}} Combine like terms on the right side.



{{{y=(-30)/(-3)}}} Divide both sides by {{{-3}}} to isolate {{{y}}}.



{{{y=10}}} Reduce.
