4b=-3x
Subtract 3x from both sides. Anything subtracted from zero gives its negation.
\frac{4b}{4}=-\frac{3x}{4}
Divide both sides by 4.
b=-\frac{3x}{4}
Dividing by 4 undoes the multiplication by 4.
3x=-4b
Subtract 4b from both sides. Anything subtracted from zero gives its negation.
\frac{3x}{3}=-\frac{4b}{3}
Divide both sides by 3.
x=-\frac{4b}{3}
Dividing by 3 undoes the multiplication by 3.
