Solve each inequality, graph each
solution, and give interval notation
a.) (a+4)-3(a+1)>-2(1-a)-5
a + 4 -3a -3 > -2 + 2a -5
-2a+1 > 2a-7
4a < 8
a < 2
Ans: (-oo,2)
------------------------
b.) -2n-4<2n+6 and (n/4)-1<-3/2
-----
4n > -10 and (n/4) < -1/2
-----
n > - 5/2 and n < -2
------
-5/2 < n < -2
------
Ans:: (-5/2,-2)
