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!
