#14. Solve:
15+=+-3%282q-1%29 First, divide both sides of the equation by -3.
15%2F%28-3%29+=+%28-3%2F-3%29%282q-1%29 Simplify.
-5+=+2q-1 Add 1 to both sides.
-5%2B1+=+2q-1%2B1 Simplify.
-4+=+2q Finally, divide both sides by 2.
%28-4%29%2F2+=+q Simplify and put the variable (q) on the left side.

#22. Solve:
x-5%2F8+=+7%2F8 Add 5/8 to both sides.
x+=+7%2F8+%2B+5%2F8
x+=+13%2F8
