Question

How do you solve `0.9x + 3> 0.6x`?

Answer 1

`x > 0.1`

Explanation:

As explained below:

`0.9x + 3 >0.6x`

Subtract `0.6x` both sides:

`0.9x-0.6x + 3 > 0.6x-0.6x`

`0.3x + 3 > 0`

Subtract `3` both sides:

`0.3x + 0.3 -0.3 > 0-0.3`

`0.3x > -0.3`

Divide by `0.3` both sides:

`(0.3x)/0.3 > -0.3/3`

`x > 0.1`

Always check you answer:
take `x = 0.2`

`0.9x + 3 >0.6x`

`0.9(0.2) + 3 > 0.6(0.2)`

`0.18 + 3 > 0.12`

`3.18 > 0.12` ----> That's right!
