Question 1016963
.
Solve inequalities (almost) just like equations: 
.
-3(a-b) > 0 . Divide each side by -3 (reverse inequality sign)
a-b < 0 . Add b to each side.
a < b
.
NOTE: Remember to reverse inequality sign when multiplying 
or dividing inequalities by a negative number.
(This is the "almost" just like equations part.)
.
Let a=1; b=2:
.
-3(a-b) > 0
-3(1-2) > 0
-3(-1) > 0
3 > 0
