Try to get the x by itself, just like a=bx + c, where you would subtract c from both sides then divide both sides by b. since the coefficient for x on both are positive, you don't have to worry about the greater than/less than signs.
so for the first, subtract 12 from both sides then divide both sides by 4. it's the same concept for the other side.

So I got x>2 for the first one and x>4 for the second one, now how does that fit into {xIx> ? }
Shouldn't it be just one number?

4x > -8 and 3x > 12
x > -2 and x > 4
so it looks like x > 4
write it in the notation asked for
