Question

What is the solution for this inequality?

8x < -32
A.
x < -4
B.
x < 4
C.
x > -4
D.
x > 4

Answer 1

The Answer is C because when u divide 8 on both sides the sign of this < would switch to > since 32 is a negative number and when u divide -32 by 8 u get x>-4

Answer 2

For this case we have the following expression:

`8x <-32`

The x must be cleared, for which the 8 (which is multiplying to the x) is passed, to the other side of the inequality, dividing to -32. So, we have left:

`x <-(32)/(8)`

Dividing we have:

`x <-4`

So, the solution is
`x <-4`

Answer:

Option A
