%281%2F5%29%2810a-15%29=3-2a Working eqn
10a%2F5-15%2F5=3-2a ---> cross%2810%292a%2Fcross%285%29-cross%2815%293%2Fcross%285%29=3-2a
2a%2B2a=3%2B3
4a=6 ----> cross%284%29a%2Fcross%284%29=6%2F4=cross%286%293%2Fcross%284%292
a=3%2F2, ANSWER
Check go back eqn:
%281%2F5%29%2810%2A%283%2F2%29-15%29=3-2%283%2F2%29
%281%2F5%29%28cross%2830%2915%2Fcross%282%29-15%29=3-cross%282%29%283%2Fcross%282%29%29
%281%2F5%29%280%29=3-3
0=0
