1-2x-\left(-1\right)-3\left(x-2\right)-4\left(x-3\right)=0
To find the opposite of 2x-1, find the opposite of each term.
1-2x+1-3\left(x-2\right)-4\left(x-3\right)=0
The opposite of -1 is 1.
2-2x-3\left(x-2\right)-4\left(x-3\right)=0
Add 1 and 1 to get 2.
2-2x-3x+6-4\left(x-3\right)=0
Use the distributive property to multiply -3 by x-2.
2-5x+6-4\left(x-3\right)=0
Combine -2x and -3x to get -5x.
8-5x-4\left(x-3\right)=0
Add 2 and 6 to get 8.
8-5x-4x+12=0
Use the distributive property to multiply -4 by x-3.
8-9x+12=0
Combine -5x and -4x to get -9x.
20-9x=0
Add 8 and 12 to get 20.
-9x=-20
Subtract 20 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-20}{-9}
Divide both sides by -9.
x=\frac{20}{9}
Fraction \frac{-20}{-9} can be simplified to \frac{20}{9} by removing the negative sign from both the numerator and the denominator.
