5x-18-\left(-x\right)>72
To find the opposite of 18-x, find the opposite of each term.
5x-18+x>72
The opposite of -x is x.
6x-18>72
Combine 5x and x to get 6x.
6x>72+18
Add 18 to both sides.
6x>90
Add 72 and 18 to get 90.
x>\frac{90}{6}
Divide both sides by 6. Since 6 is positive, the inequality direction remains the same.
x>15
Divide 90 by 6 to get 15.
