{{{4+7a=9+4a}}} Start with the given equation.



{{{7a=9+4a-4}}} Subtract {{{4}}} from both sides.



{{{7a-4a=9-4}}} Subtract {{{4a}}} from both sides.



{{{3a=9-4}}} Combine like terms on the left side.



{{{3a=5}}} Combine like terms on the right side.



{{{a=(5)/(3)}}} Divide both sides by {{{3}}} to isolate {{{a}}}.
