a\left(3c-5\right)=2b+4
Multiply both sides of the equation by 3c-5.
3ac-5a=2b+4
Use the distributive property to multiply a by 3c-5.
2b+4=3ac-5a
Swap sides so that all variable terms are on the left hand side.
2b=3ac-5a-4
Subtract 4 from both sides.
\frac{2b}{2}=\frac{3ac-5a-4}{2}
Divide both sides by 2.
b=\frac{3ac-5a-4}{2}
Dividing by 2 undoes the multiplication by 2.
b=\frac{3ac}{2}-\frac{5a}{2}-2
Divide 3ac-5a-4 by 2.
