.
3p%2F7=4%2F5 Multiply each side by 7.
3p=28%2F5 Multiply each side by 5.
15p=28 Divide each side by 15.
p=28%2F15
.
%282y%29%2B%281%2F2%29y=%283%2F2%29 Factor out y on left side.
%28y%29%282%2B1%2F2%29=3%2F2 Find common denominator on left.
%28y%29%284%2F2%2B1%2F2%29=3%2F2 Combine like terms.
y%285%2F2%29=3%2F2 Multiply each side by 2.
5y=3 Divide each side by 5.
y=3%2F5
