4+6+6x=26+2x
Use the distributive property to multiply 2 by 3+3x.
10+6x=26+2x
Add 4 and 6 to get 10.
10+6x-2x=26
Subtract 2x from both sides.
10+4x=26
Combine 6x and -2x to get 4x.
4x=26-10
Subtract 10 from both sides.
4x=16
Subtract 10 from 26 to get 16.
x=\frac{16}{4}
Divide both sides by 4.
x=4
Divide 16 by 4 to get 4.
