5x+16 greater than 1 and 2x-21 greater than -17.
5x + 16 > 1
Subtract 16 from both sides.
5x > -15
Divide both sides by 5. (You solve just like an equation, except If you multiply/divide by a negative value, then you have to reverse the carat.)
x > -3
Use the same principles to solve the second inequality.
