2x-4-\left(-x\right)\leq -1
To find the opposite of 4-x, find the opposite of each term.
2x-4+x\leq -1
The opposite of -x is x.
3x-4\leq -1
Combine 2x and x to get 3x.
3x\leq -1+4
Add 4 to both sides.
3x\leq 3
Add -1 and 4 to get 3.
x\leq \frac{3}{3}
Divide both sides by 3. Since 3 is positive, the inequality direction remains the same.
x\leq 1
Divide 3 by 3 to get 1.
