or, not and
solve each seperately
6b<24
divide both sides by 6
b<4
4b+12>4
minus 12 both sides
4b>-8
divide by 4
b>-2
b<4 or b>-2
b>-2 or b<4
if we graph each on a number line, they go in oposite directions
since it is OR, the solution must satisfy one OR the other, doesn't have to be both
graph looks like this
therfor answer is all real numbers
