You can put this solution on YOUR website! .
You start with this inequality
2x - 2 <= 7 - x
Add x to both sides and combine like terms. You will get then
3x - 2 <= 7.
Now add 2 to both sides and combine like terms. You will get
3x <= 9
Finally, divide both sides by 3. You will get the answer
x <= 3.
Now you decide if 4 is the solution to the given inequality.
Solved.
