Question

Solve the inequalities 1. t-7<-152. b+12<18

Answer 1

Inequalities are just like equations it's just that the sign flips anytime you multipliy or divide by a negative number

1.
$t - 7 < - 15$
First Add 7 to both sides
$t + (-7 + 7)< ( - 15 + 7) \\ t < - 8$
2.
$b + 12 < 18$
First Subtract 12 From Both Sides
$b + (12 - 12) < (18 - 12) \\ b < 6$
