y=cx+N

Rewrite the equation as cx+N=y.

cx+N=y

Subtract N from both sides of the equation.

cx=y-N

Divide each term in cx=y-N by c.

cxc=yc+-Nc

Cancel the common factor of c.

Cancel the common factor.

cxc=yc+-Nc

Divide x by 1.

x=yc+-Nc

x=yc+-Nc

Move the negative in front of the fraction.

x=yc-Nc

x=yc-Nc

Solve for x y=cx+N
