Question

Please answer. Which is the graph of the solutions.

Answer 1

3rd option from the top (open circle arrow going left)

Explanation:

5(2x-4) is less than - 100

5 times 2x is 10x and 5 times - 4 is - 20 so,

10x - 20 is less than - 100

now do inverse operations to isolate x, add 20

- 20 plus 20 is 0 and -100 plus 20 is - 80

10x is less than -80

divide both sides by 10 and you get,

x is less than - 8

Answer 2

x < -8, third from top option in the picture.

Explanation:

5(2x - 4) < -100

10x - 20 < -100

10x < -80

x < -8
