3-6-\left(-x\right)=4x
To find the opposite of 6-x, find the opposite of each term.
3-6+x=4x
The opposite of -x is x.
-3+x=4x
Subtract 6 from 3 to get -3.
-3+x-4x=0
Subtract 4x from both sides.
-3-3x=0
Combine x and -4x to get -3x.
-3x=3
Add 3 to both sides. Anything plus zero gives itself.
x=\frac{3}{-3}
Divide both sides by -3.
x=-1
Divide 3 by -3 to get -1.
