5\times 14xy=28
Multiply both sides of the equation by 80, the least common multiple of 16,20.
70xy=28
Multiply 5 and 14 to get 70.
70yx=28
The equation is in standard form.
\frac{70yx}{70y}=\frac{28}{70y}
Divide both sides by 70y.
x=\frac{28}{70y}
Dividing by 70y undoes the multiplication by 70y.
x=\frac{2}{5y}
Divide 28 by 70y.
5\times 14xy=28
