2x+3x+1+4x+2=13\times 3
Multiply both sides by 3.
5x+1+4x+2=13\times 3
Combine 2x and 3x to get 5x.
9x+1+2=13\times 3
Combine 5x and 4x to get 9x.
9x+3=13\times 3
Add 1 and 2 to get 3.
9x+3=39
Multiply 13 and 3 to get 39.
9x=39-3
Subtract 3 from both sides.
9x=36
Subtract 3 from 39 to get 36.
x=\frac{36}{9}
Divide both sides by 9.
x=4
Divide 36 by 9 to get 4.
