-8 >= -5x + 2 > -38
OpenStudy (solomonzelman):
−8 greater than or equal to −5x + 2 > −38 --->
-8≥ -5x+2>-38

@0037109, can you solve for x?
OpenStudy (solomonzelman):
-8≥ -5x+2>-38
OpenStudy (aggie12341):
Because you substact 2 on each side and get -5x=-40. Then divide -5 on each side and get x<8
OpenStudy (anonymous):
where is the graph??

DO IT YOURSELF KID...

@aggie12341, you can't fish for medals like this.
6≥ 4x+2>10
subtract 2 from all both sides, to eliminate the x.
6-2≥ 4x+2-2>10-2
4≥ 4x>8
divide everything by 4 to get rid of the x 's coefficient, there is your answer.
1≥ x>2
to graph it,

CAN YOU DO YOUR EXAMPLE?
