Remember, you can do anything to an equation as long as you do it to both sides but, for inequalities, if you multiply or divide both sides by a negative, you flip the sign
70+5x<30+15x minus 5x both sides 70<30+10x minus 30 both sides 40<10x divide both sides by 10 4<x
x>4 is the solution set
a real world problem could be
company A charges a flat rate of $70 dollars to rent their car and also charge a rate of $5 per mile driven
company B charges a flat rate of $30 dollars to rent the car and also charge $15 per mile
how many miles do you have to drive for you to pay more for company B than A?
