2x+c=22
Multiply both sides of the equation by 2.
c=22-2x
Subtract 2x from both sides.
2x+c=22
Multiply both sides of the equation by 2.
2x=22-c
Subtract c from both sides.
\frac{2x}{2}=\frac{22-c}{2}
Divide both sides by 2.
x=\frac{22-c}{2}
Dividing by 2 undoes the multiplication by 2.
x=-\frac{c}{2}+11
Divide 22-c by 2.
