How do I solve the inequality 7x+2 > 2x-3?
Treat the > as an = and solve the equation as you normally would. So for the inequality 7x+2 > 2x-3, pretend it was 7x+2 = 2x-3 and solve that. Just make sure you always replace where you'd write an = with a > . The only thing you aren't allowed to do is multiply by a negative number - we'll do example with that later
