kx+2k+4=y
Swap sides so that all variable terms are on the left hand side.
kx+2k=y-4
Subtract 4 from both sides.
\left(x+2\right)k=y-4
Combine all terms containing k.
\frac{\left(x+2\right)k}{x+2}=\frac{y-4}{x+2}
Divide both sides by x+2.
k=\frac{y-4}{x+2}
Dividing by x+2 undoes the multiplication by x+2.
kx+2k+4=y
Swap sides so that all variable terms are on the left hand side.
kx+4=y-2k
Subtract 2k from both sides.
kx=y-2k-4
Subtract 4 from both sides.
\frac{kx}{k}=\frac{y-2k-4}{k}
Divide both sides by k.
x=\frac{y-2k-4}{k}
Dividing by k undoes the multiplication by k.
