4x+3y=-7
Multiply both sides of the equation by 12, the least common multiple of 3,4,12.
4x=-7-3y
Subtract 3y from both sides.
4x=-3y-7
The equation is in standard form.
\frac{4x}{4}=\frac{-3y-7}{4}
Divide both sides by 4.
x=\frac{-3y-7}{4}
Dividing by 4 undoes the multiplication by 4.
4x+3y=-7
Multiply both sides of the equation by 12, the least common multiple of 3,4,12.
3y=-7-4x
Subtract 4x from both sides.
3y=-4x-7
The equation is in standard form.
\frac{3y}{3}=\frac{-4x-7}{3}
Divide both sides by 3.
y=\frac{-4x-7}{3}
Dividing by 3 undoes the multiplication by 3.
