Solve for S:
%28S-3%29%2F7+=+%28S%2B5%29%2F9 Multiply both sides by 7 and by 9.
9%28S-3%29%2Across%287%29%2Fcross%287%29+=+7%28S%2B5%29%2Across%289%29%2Fcross%289%29 Cancel as indicated.
9%28S-3%29+=+7%28S%2B5%29 Perform the distributive property.
9S-27+=+7S%2B35 Add 27 to both side.
9S+=+7S%2B62 Subtract 7S from both sides.
2S+=+62 Divide both sides by 2.
