Question 568549
{{{9a+2=4a-18}}} Start with the given equation.



{{{9a=4a-18-2}}} Subtract {{{2}}} from both sides.



{{{9a-4a=-18-2}}} Subtract {{{4a}}} from both sides.



{{{5a=-18-2}}} Combine like terms on the left side.



{{{5a=-20}}} Combine like terms on the right side.



{{{a=(-20)/(5)}}} Divide both sides by {{{5}}} to isolate {{{a}}}.



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