Question

Solve the inequalities
1. t-7<-15
2. 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`
