Question

Solve the compound inequality 6b < 24 or 4b + 12 > 4.

b < 4 or b > −2

b < 4 or b > 4

b < 4 or b > 2

b > 4 or b < −2

Answer 1

6b < 24 or 4b + 12 > 4
b<24/6 or 4b>4-12
b<4 or 4b>-8
b<4 or b>-2

Answer 2

Set them up into two different inequalities

6b < 24
Divide by 6 on both sides
b < 4

4b + 12 > 4
Subtract 12 from both sides
4b > -8
Divide by 2 on both sides
b > -2

b<4 or b>-2
