Its d!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
The answer for the first equation is,
X = 6, -4
The answer for second equation is,
X = 9,2
Y - 4.5 = 12.2
your solving for y which means your trying to get rid of 4.5 so that y can equal something. The opposite of -4.5 would be +4.5, so you would add 4.5 to both sides to get
y = 16.7
So your answer would be
A. Add 4.5
and also dont' say your stupid because all you need is a little explanation and you'll get it, its very easy you just need to take the time to practice :-)
