OpenStudy (anonymous):

are solving for x?

OpenStudy (anonymous):

-5/4<x<9/4

OpenStudy (anonymous):

aka -1.25<x<2.25

OpenStudy (anonymous):

u want 2 get x by itself in the middle, but remember to add/subtract/multiply/whatever to all three sides of the equation. So if you add the 8 out, you add it to the 1 and the -13

OpenStudy (anonymous):
