Solve the inequality 5x+3<3x-6
We need to solve this so we have a positive x term on one side.
First we can subtract 3 from both sides of the inequality to get:
5x<3x-9
Next we can subtract 3x from both sides to get:
2x<-9
Finally we can divide both sides by 2 to get:
x<-4.5
This gives us our possible values of x.
