5/2(a+2) <-6 and 3/4(a-2)<1

I am stuck.. so far I did 5/2 x (a+2)/1 ... I believe that is correct so far but it seems wrong.

Wouldn't it be... 5(a+2)=2 but I am unsure how this plugs back into 5/2(a+2) <-6

Also confused on this one..... -1 < -2x + 4 less than or equal to 5, and this does split into 2 equations?

is it right to look like -5<-2x?
