4x+2\left(-x\right)+1=x+13
Add 10 and 3 to get 13.
4x+2\left(-x\right)+1-x=13
Subtract x from both sides.
3x+2\left(-x\right)+1=13
Combine 4x and -x to get 3x.
3x+2\left(-x\right)=13-1
Subtract 1 from both sides.
3x+2\left(-x\right)=12
Subtract 1 from 13 to get 12.
3x-2x=12
Multiply 2 and -1 to get -2.
x=12
Combine 3x and -2x to get x.
