                Solving for the sytems of equiation using the elimination method.
Book gives answers 3,2. I have tried using all the numbers to solve for x and y.
I do get the 3,2. Don't know if this is another error in the book.
8x-4y=16
4x+5y=22

    leave the first equation, but multiply the second by 2
8x-4y=16
8x+10y=44 , now subtract them
-14y = -28
y=2
back into the first
8x - 8 = 16
8x = 24
x=3
so x=3, y=2 like the textbook had
