Question

How do you solve `15>= 8 + b - 12`?

Answer 1

`b<=19`

Explanation:

Treat inequalities in the same way as equations, except if you multiply or divide by a negative number, then the inequality sign has to change around.

`" "15 >=8 + b- 12`

`15+12-8 >=b`

`" "19 >=b`

This is easier written as `b<=19`
