I'll get you started

3(x+4)-5(-1)<5

3(x)+3(4)-5(-1)<5 ... distribute

3x+12+5<5 ... multiply

3x+17 < 5 ... combine like terms


See how to finish up?

x>-4

jim_thompson5910 · Answer

notice in the original problem, the inequality sign is <

how did you get a > sign?

comm.dan · Answer

I switched it because my math teacher told our class that we have to switch the inequality sign no matter which grouping symbol it is.
