x-2\left(x-3x+12\right)=1
Use the distributive property to multiply -3 by x-4.
x-2\left(-2x+12\right)=1
Combine x and -3x to get -2x.
x+4x-24=1
Use the distributive property to multiply -2 by -2x+12.
5x-24=1
Combine x and 4x to get 5x.
5x=1+24
Add 24 to both sides.
5x=25
Add 1 and 24 to get 25.
x=\frac{25}{5}
Divide both sides by 5.
x=5
Divide 25 by 5 to get 5.
