Question 823193
{{{1+9a+15=16a}}} Start with the given equation.



{{{9a+16=16a}}} Combine like terms on the left side.



{{{9a=16a-16}}} Subtract {{{16}}} from both sides.



{{{9a-16a=-16}}} Subtract {{{16a}}} from both sides.



{{{-7a=-16}}} Combine like terms on the left side.



{{{a=(-16)/(-7)}}} Divide both sides by {{{-7}}} to isolate {{{a}}}.



{{{a=16/7}}} Reduce.
