math
add -3/4 to -3/4 to cancel it out then ass -3/4 to -6 so you have 1/4x=-1.5 divide 1/4 by 1/4 to get the x alone then divide -1.5 by 1/4 and whatever that comes out to be equals x

6/6=1 so there is 6 1/6 in one and 3/6=1/2 so there is 3 1/6 in 1/2

math.
-0.2x<-12 -0.2/-0.2 to get x alone then -12/-0.2=-60 so x=-60

math
yes
