Question

3(5x – 10) < 30x solve for x

Answer 1

x>-1.25

Explanation:

3(5x-10)<30x

15x-20<30x

-20<15x

-20/15<x

-1.25<x

x>-1.25

Answer 2

Explanation:

Step 1: Distribute

`3(5x - 10) < 30x`

`(3 * 5x) + (3 * -10) < 30x`

`15x - 30 < 30x`

Step 2: Subtract 15x from both sides

`15x - 15x - 30 < 30x - 15x`

`-30 < 15x`

Step 3: Divide both sides by 15

`-30 / 15 < 15x / 15`

`-2 < x`

Answer:
`x > -2`
