Question 640497
{{{7-y-y=-1}}} Start with the given equation.



{{{-2y+7=-1}}} Combine like terms on the left side.



{{{-2y=-1-7}}} Subtract {{{7}}} from both sides.



{{{-2y=-8}}} Combine like terms on the right side.



{{{y=(-8)/(-2)}}} Divide both sides by {{{-2}}} to isolate {{{y}}}.



{{{y=4}}} Reduce.
