Rewrite the problem with improper fractions:
-2%2F3+=+f%2F6+%2B+3%2F2+

The LCD = 6, so multiply both sides by 6:
6%2A%28-2%2F3%29+=+6%2A%28f%2F6%29+%2B+6%2A%283%2F2%29+

-4+=+f+%2B+9

Subtract 9 from each side:
-4+-+9+=+f%2B9-9
-13+=+f+

Check:
-2%2F3+=+f%2F6+%2B+3%2F2+
-2%2F3+=+-13%2F6+%2B+3%2F2+
%28-2%2F3%29%2A%282%2F2%29+=+-13%2F6+%2B+%283%2F2%29%2A%283%2F3%29+
-4%2F6+=+-13%2F6+%2B+9%2F6
-4%2F6+=+-4%2F6
