If x = 3 and y = 4 then the answer is 2
0
x + 2y = 83x - y = 3Need to rearrange first for easier calculation (get y and x on different sides) so...x + 2y = 8 is the same as 2y = 8 - x is the same as y = 4 - 0.5x3x - y = 3 is the same as y = 3x - 3Lines intersect when the functions equal each othery=y4 - 0.5x = 3x - 37 - 0.5x = 3x7 = 3.5x2 = xput x value into either equation to find y valuey = 3(2) - 3y = 3Lines intersect at point (2,3)

y + y4 = y5 , possibly. Except that conventionally, the number (or coefficient) would be written first. y + y4 = y*(1 + y3) = y(1 + y)*(1 - y + y2)
(x2 + y2)(x + y)(x - y) = x4 - y4.
(y^2 + 8)(y^2 + 2)
If x = 3 and y = 4 then the answer is 2
y4 times y3 = y7
y4.
If 2x-y = 4 then 6x -3 years =?
y4

y4 - 256 = (y2 - 16)(y2 + 16) = (y - 4)(y + 4)(y2 + 16)
