Question

How do you solve `12(10b -9) > -12(9+8b)`?

Answer 1

`b>0`

Explanation:

`12(10b-9)> -12(9+8b)`
Divide both sides by 12:
`(10b-9) > - (9+8b)`
On the right side distribute the negative sign inside parentheses:
`10b-9> -9 -8b`
Add 9 to both sides:
`10b > -8b`
Add 8b to both sides:
`18b>0`
Divide both sides by 18:
`b>0`
In interval form:
`(0, oo)`
