So A) First you replace the Y's with -0.5 because it says that y= -0.5.
Second BEDMAS brackets first.
Almost Done. C) First replace the Q's with -3.6
Second. First I thought that you subtract fractions, but then i remembered that we haven't learned how to subtract fractions THIS year yet.
So you divide the decimals. 4.5/ -3.6 - -3.6/4.5
Okay so there it is. Sorry for it being so long. Comment please.
