Question

The sum of a number x and -7 is less than or equal to 18.
Write and solve each inequality

Answer 1

x≤ 25.

Explanation:

SO basically, the equation is x+-7≤ 18. What you do is you use the equation to solve for x. So, x+-7 is the same as x-7, so what you do is you add 7 from both sides to get x≤ 25.

Hope this helps:)
