-x-\left(-4\right)-x=1
To find the opposite of x-4, find the opposite of each term.
-x+4-x=1
The opposite of -4 is 4.
-2x+4=1
Combine -x and -x to get -2x.
-2x=1-4
Subtract 4 from both sides.
-2x=-3
Subtract 4 from 1 to get -3.
x=\frac{-3}{-2}
Divide both sides by -2.
x=\frac{3}{2}
Fraction \frac{-3}{-2} can be simplified to \frac{3}{2} by removing the negative sign from both the numerator and the denominator.
