Question

Solving inequalities( need help checking my answer)

Answer 1

Step 1. You need x isolated.

`x < 13+7`

When you move a number from the left to right (and its addition or subtraction, the sign stays (< ≤ > and ≥ is signs).
x<20 or in words, x is less than 20, and cannot be 20.

Answer 2

x < 20

Any number less than 20 is a solution

Explanation:

x-7 < 13

The first step to solve this inequality is to add 7 to each side

x-7+7 < 13+7

x < 20

Any number less than 20 is a solution
