I need help solving an inequality. 2x+4 is greater than or equal to x+7

OpenStudy (blondie_b23):

First, I subtracted 2x from both sides.

OpenStudy (blondie_b23):

So, I got 4 greater than or equal to x plus 7

OpenStudy (blondie_b23):

*-x

OpenStudy (blondie_b23):

I'm not even sure this is right, or where to go from here.

OpenStudy (taylor0402):

what grade ore you in?

OpenStudy (blondie_b23):

The answer must be in interval notation. I am in 9th.

OpenStudy (blondie_b23):

I originally got [3, infinity)

OpenStudy (blondie_b23):

Something must be wrong in my math though.

OpenStudy (blondie_b23):

Help if you can.

Sorry, I got an answer that I too do not understand. |dw:1473096907367:dw|
