7 + 5 is 12 so half of five ( 5$ is the price of two sides ) is 2 1/2 and 2 1/2 is the price of one side.
( sorry if it is confusing ^O^ )
Start with

We observe that both fractions are not defined if
. So, we will assume
.
We multiply both numerator and denominator of the first fraction by 3 and we sum the two fractions:

We multiply both sides by
:

We move everything to one side and solve the quadratic equation:

We check the solution:

which is true
