7xy+0y\times 7x=3
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 7x.
7xy+0yx=3
Multiply 0 and 7 to get 0.
7xy+0=3
Anything times zero gives zero.
7xy=3
Anything plus zero gives itself.
7yx=3
The equation is in standard form.
\frac{7yx}{7y}=\frac{3}{7y}
Divide both sides by 7y.
x=\frac{3}{7y}
Dividing by 7y undoes the multiplication by 7y.
x=\frac{3}{7y}\text{, }x\neq 0
Variable x cannot be equal to 0.
7xy+0y\times 7x=3
Multiply both sides of the equation by 7x.
7xy+0yx=3
Multiply 0 and 7 to get 0.
7xy+0=3
Anything times zero gives zero.
7xy=3
Anything plus zero gives itself.
\frac{7xy}{7x}=\frac{3}{7x}
Divide both sides by 7x.
y=\frac{3}{7x}
Dividing by 7x undoes the multiplication by 7x.
