#x > 0.1#

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!
