42x=7y
The equation is in standard form.
\frac{42x}{42}=\frac{7y}{42}
Divide both sides by 42.
x=\frac{7y}{42}
Dividing by 42 undoes the multiplication by 42.
x=\frac{y}{6}
Divide 7y by 42.
7y=42x
Swap sides so that all variable terms are on the left hand side.
\frac{7y}{7}=\frac{42x}{7}
Divide both sides by 7.
y=\frac{42x}{7}
Dividing by 7 undoes the multiplication by 7.
y=6x
Divide 42x by 7.
