Answer:
c - 7 ≤ 17
c ≤ 24
Explanation:
The difference of c and 7 can be written as c - 7 or 7 - c.
Now, since c - 7 is less than or equal to 17, you need to add ≤ to imply that it's less than or equal to 17.
As always, write the 17 on the other side. Now you have an inequality.
If you just need the equation, it's c - 7 ≤ 17.
But if you want to solve for c, it would be c ≤ 24.
(bring the like terms together and isolate c.)
