Question 897250
{{{7+4a=8(a+4)}}} Start with the given equation.



{{{7+4a=8a+32}}} Distribute.



{{{4a=8a+32-7}}} Subtract {{{7}}} from both sides.



{{{4a-8a=32-7}}} Subtract {{{8a}}} from both sides.



{{{-4a=32-7}}} Combine like terms on the left side.



{{{-4a=25}}} Combine like terms on the right side.



{{{a=(25)/(-4)}}} Divide both sides by {{{-4}}} to isolate {{{a}}}.



{{{a=-25/4}}} Reduce.
