Question 599302
{{{7a-3=2a+9-a}}} Start with the given equation.



{{{7a-3=a+9}}} Combine like terms on the right side.



{{{7a=a+9+3}}} Add {{{3}}} to both sides.



{{{7a-a=9+3}}} Subtract {{{a}}} from both sides.



{{{6a=9+3}}} Combine like terms on the left side.



{{{6a=12}}} Combine like terms on the right side.



{{{a=(12)/(6)}}} Divide both sides by {{{6}}} to isolate {{{a}}}.



{{{a=2}}} Reduce.
