Yeah so i forgot how you do stuff like this.

{ 2x<4
4-x<1

this is just a real basic example. (The { should cover both equations)

What... graph them? solve for x?

In this case, for the first guy, 2x < 2 ==> x < 2 and 4 - x < 1 ==> x > -3.

Wah?
First one, 2x < 4 ==> x < 2
Second one 4 - x < 1 ==> x >+3

Its pretty much the same as normaly algebra but like, when you divide by a minus, you switch the inequality.

Don't forget that if you divide by a negative number, you have to switch the inequality around.

TS wrote 2x<4, not 2x<2, so Darkstar is right on that.
And the 2nd one is +3.
