Hello there!
Our goal is to isolate the variable on one side of the inequality, and then solve for it.
1.) 5x + 3

-17
Subtract 3 from both sides to isolate the variable.
5x

-20
Divide 5 from both sides to solve for the variable.
x

-4 is your first inequality solution for the first inequality.
2.) 14x + 20

13
Subtract 20 from both sides to isolate the variable.
14x

-7
Divide both sides by 14 to solve for the variable.
x

is your solution for the second inequality.
I hope this helps!
