Question

1. [02.05]

Solve for x: -2x - 4 > 8
A)x<-6
B)x>-6
C)x<-2
D)X > -2

Answer 1

x < -6

Explanation:

-2x - 4 > 8

Add left and right of the > sign by 4.

-2x -4 +4 > 8 +4

-2x +0 > 12

-2x > 12

Divide left and right of the > sign by MINUS 2, and remember that will flip the sign!

(-2/-2)x < (12/-2)

x < -6
