how do u do this 5x−4≥12 AND 12x+5≤−4

dude:

Do you want to algebraically solve this or use a graph?

adevanath:

@dude what do u mean

dude:

Do you want to graph the inequality or solve for the possible x values that can go into this equation?

adevanath:

just the equation

dude:

lol okay that doesn't make sense, equations are not inequalities So you want to solve both equations?

adevanath:

yes

dude:

5x−4≥12 \(∪\) 12x+5≤−4 Lets solve the first equation first 5x−4≥12 Do you know how to start off?

adevanath:

add 4 to both sides i think

dude:

Yes \(5x\ge12\) Do you know what to do from here?

adevanath:

yup

dude:

Yes and that is?
