Question

How do you solve the inequality 12 < x + 5 so that the variable "x" is on the left side?

Answer 1

The like terms are 12 and 5, so you have to subtract 5 from both sides.
12 < x + 5
-5. -5
7 < x
We can just switch it around so x is in the left side.
x > 7

Answer 2

12<x+5
=12-5<x
=7<x
we can just switch it and it becomes x>7
