Question 987052
{{{5(y-4)=7(2y+1)}}} Start with the given equation.



{{{5y-20=14y+7}}} Distribute.



{{{5y=14y+7+20}}} Add {{{20}}} to both sides.



{{{5y-14y=7+20}}} Subtract {{{14y}}} from both sides.



{{{-9y=7+20}}} Combine like terms on the left side.



{{{-9y=27}}} Combine like terms on the right side.



{{{y=(27)/(-9)}}} Divide both sides by {{{-9}}} to isolate {{{y}}}.



{{{y=-3}}} Reduce.

Answer:


So the solution is {{{y=-3}}}
