5x+4≥2x-8

OpenStudy (inkyvoyd):

First, isolate the variable. How would you do that?

OpenStudy (anonymous):

by subtracting 2 from both sides and adding 4 to bth sides?

OpenStudy (inkyvoyd):

You'll want to subtract 2x from both sides, and then subtract 4, actually.

OpenStudy (anonymous):

then divide 3 from both sides?

OpenStudy (inkyvoyd):

5x+4-2x≥2x-8-2x 3x+4-4≥0-8-4

OpenStudy (inkyvoyd):

Yes.

OpenStudy (anonymous):
