4x-7=-3y
Subtract 3y from both sides. Anything subtracted from zero gives its negation.
4x=-3y+7
Add 7 to both sides.
4x=7-3y
The equation is in standard form.
\frac{4x}{4}=\frac{7-3y}{4}
Divide both sides by 4.
x=\frac{7-3y}{4}
Dividing by 4 undoes the multiplication by 4.
3y-7=-4x
Subtract 4x from both sides. Anything subtracted from zero gives its negation.
3y=-4x+7
Add 7 to both sides.
3y=7-4x
The equation is in standard form.
\frac{3y}{3}=\frac{7-4x}{3}
Divide both sides by 3.
y=\frac{7-4x}{3}
Dividing by 3 undoes the multiplication by 3.
