Solve for x: −2x + 5 < 7 A. x > −1 B. x < −1 C. x > −6 D. x < −6

OpenStudy (calculusxy):

This is basically like solving for x in an equation, except that you have an inequality sign.

Nnesha (nnesha):

1) subtract or add 2) divide or multiply when you multiply by negative number you must flip the inequality

OpenStudy (calculusxy):

-2x + 5 < 7 Start off with the constant.

OpenStudy (alexandervonhumboldt2):

subtratc 5 from both sides: -2x+5-5<7-5 you get -2x<2 now just divide both sides by -2 and get the answer but you also need to flip the sing to >

OpenStudy (anonymous):

So it would be x > -1?

OpenStudy (alexandervonhumboldt2):

yes

OpenStudy (calculusxy):
