If there is 23 classrooms and each has 10 then you would have to times 23 by 10 - 23x10=230
X=2y
2x+5y=9
substitute the x=2y into the second equation
2(2y)+5y=9
multiple the 2y by 2. 4y+5y=9
combine like terms. 9y=9
divide the 9 out from both sides. y=1
plug the y back into the first equation
x=2(1)
multiply. x=2
your answer is: x=2
y=1
The answer is 2.36 :) :) :) :) :)
