7x-14+3-x-7=0
Use the distributive property to multiply 7 by x-2.
7x-11-x-7=0
Add -14 and 3 to get -11.
6x-11-7=0
Combine 7x and -x to get 6x.
6x-18=0
Subtract 7 from -11 to get -18.
6x=18
Add 18 to both sides. Anything plus zero gives itself.
x=\frac{18}{6}
Divide both sides by 6.
x=3
Divide 18 by 6 to get 3.
