You can put this solution on YOUR website!
6/7y-1/3=1/5
Multiply by 7*3*5 to eliminate fractions.
90y - 35 = 21
Add 35
90y = 56
Divide by 90
y = 56/90
y = 28/45

i dont like fractions so first thing i do is multiply the denominators together
7y * 3 * 5 = 105y
now multiply everything by 105y
%28105y%29%286%2F7y%29-%28105y%29%281%2F3%29=%28105y%29%281%2F5%29

%2815%2A6%29-%2835y%29=21y
90-35y=21yadd 35y to both sides
90=56y divide by 56
90%2F56=y reduce by 2
45%2F28=y
