size 3y is 3 youth.
3y
The size for the medium nike elite socks are from 6-8.
x = 3y x - 3y = 3y - 3y x - 3y = 3y - 3y x - 3y = 0
It is the same as: 12y^2 -3xy
3y +3y = 6y
Like terms are terms with the same variable to the same power. Examples: 2y and 3y are like terms. 2y and 2z are not like terms 4y squared and 3y squared are like terms 4y squared and 3y are not like terms
3y + 4z + 12y = 3y -3y -3y ------------------------- 4z + 12y = 0 divide everything by 4 z + 3y = 0 -3y -3y z = -3y
The equation for 3y + 3y = -1 is 3y + 3y = -1.
x-3y=3 is the same as -3y=-x+3 and now divide by -3 and you have y=(1/3)x-1 which is the slope intercept form.
4x + 3y = 5.60 2x + 3y = 4.60 4x + 3y = 5.60 -2x - 3y = -4.60 ------------------------ 2x = 1.00 x = .50 <==cost of pencil 2x + 3y = 4.60 2(.50) + 3y = 4.60 1 + 3y = 4.60 3y = 3.60 y = $1.20 <==cost of pen Pencils are $.50 and pens are $1.20 <==ANSWER
(3y2 - 3y)/(y - 1) = 3y(y - 1)/(y - 1) = 3y
