Question

What is The solution to -122 < -3(-2 - 8x) - 8x

A. x<8
B. x<-2
C. x>5
D. x>-8

Answer 1

D.

Explanation:

We can solve by simply isolating x:

`-122 < -3(-2-8x)-8x\\-122 < 6+24x-8x\\-122 < 6+16x\\-128 < 16x\\-8 < x\\OR\\x > -8`

You can check by plugging in any value greater than -8

-122<-3(-2-8(-7))-8*-7

-122<-3(-2+56)+56

-122<-3(54)+56

-122<-162+56

-122<-106

Answer 2

the answer would be B
