x=x-4/y
0=-4/y
0=-4
This equation is not well put together. I may have interpreted it wrong. This may be your equation and you didn't state that x-4 is a quantity
x=(x-4)/y
x-4=xy
y=1-4/x
y=-4x-1 + 1
This is slope intercept form. Your slope is -4/1 and your y-intercept is +1
Y = 4/x^2
You would need one more equation relation x and y to solve for both of them.
v/7x = w/y Multiply both sides of the equation by x, to get: v/7 = xw/y Multiply both sides of this equation by y/w, to get: vy/7w = x .
It depends on how y depends on x.
xy = x ÷x y = 1
y=x+2if y=66=x+26-2=x4=xso x=4
(x4 + y4)/(x + y) = Quotient = x3 - x2y + xy2 - y3 Remainder = - 2y4/(x+y) So, x3 - x2y + xy2 - y3 - 2y4/(x+y)
(x2 + y2)(x + y)(x - y) = x4 - y4.
x2 / y = (6)2 /2 = 36/2 = 18
Y = 4/x^2
0.6667
y = mx + b
(x + y)2 = x2 + 2xy + y2 So x2 + y2 = (x + y)2 - 2xy = a2 - 2b Then (x2 + y2)2 = x4 + 2x2y2 + y4 So x4 + y4 = (x2 + y2)2 - 2x2y2 = (a2 - 2b)2 - 2b2 = a4 - 4a2b + 4b2 - 2b2 = a4 - 4a2b + 2b2
Sorry but i dont know te answer to this :( x/a= y/b therefore x = ay/b
You would need one more equation relation x and y to solve for both of them.
Y / (2+x)If x = -1 and y=2, thenY / (2+x) = 2/(2-1) = 2/1 = 2
