Question

What is the solution to this inequality: 8x < -32

Answer 1

x < -4 or (-∞,-4)

Explanation:

to solve 8x < -32, we treat the inequality symbol as an = sign and solve it like we would any other equation: get x alone

8x < -32 < divide both sides by 8 to isolate x

8x/8 = x

-32/8 = -4

x < -4 is our solution

in interval notation this can be written as (-∞, -4)
