I can't figure out this inequality 5 + 5 (x + 4) < 20. Any tips on how I can solve?

Remember you can do anything to an equation or inequality as long as ou do it to both sides

also, when multiplying by a negative number in an inequality, don't forget to flip the sign

5+5 (x+4) <20

minus 5 from both sides

5 (x+4) <15

divide both sides by 5

x+4<3

minus 4 from both sides

x<-1
