4k+b=6
Swap sides so that all variable terms are on the left hand side.
b=6-4k
Subtract 4k from both sides.
4k+b=6
Swap sides so that all variable terms are on the left hand side.
4k=6-b
Subtract b from both sides.
\frac{4k}{4}=\frac{6-b}{4}
Divide both sides by 4.
k=\frac{6-b}{4}
Dividing by 4 undoes the multiplication by 4.
k=-\frac{b}{4}+\frac{3}{2}
Divide 6-b by 4.
