4x=7+y
Add y to both sides.
4x=y+7
The equation is in standard form.
\frac{4x}{4}=\frac{y+7}{4}
Divide both sides by 4.
x=\frac{y+7}{4}
Dividing by 4 undoes the multiplication by 4.
-y=7-4x
Subtract 4x from both sides.
\frac{-y}{-1}=\frac{7-4x}{-1}
Divide both sides by -1.
y=\frac{7-4x}{-1}
Dividing by -1 undoes the multiplication by -1.
y=4x-7
Divide 7-4x by -1.
