We want to solve 9a² = 16a for a.
Because the a is on both sides, a good strategy is to get all the a terms on one side and set it equal to zero. Then we apply the Zero Product Property (if the product is zero then so are its pieces and Factoring.
9a² = 16a
9a² - 16a = 0                <-----subtract 16a from both sides
a (9a - 16) = 0               <-----factor the common a on the left side
a = 0   OR   9a - 16 =0   <----apply Zero Product Property
Since a = 0 is already solved we work on the other equation.
9a - 16 = 0
9a = 16                        <----------- add 16 to both sides
a = 16/9                       <----------- divide both sides by 9
Thus a = 0 or a = 16/9

Answer:
x + (x-42.2) = 90
2x - 42.2 = 90
add 42.2 to both sides
2x = 132.2
divide each side by 2
x = 66.1
find the measure of the other angle
66.1 - 42.2 = 23.9
