4xy+1=3y-7x 4xy-3y=-7x-1 y(4x-3)=-7x-1 y=(-7x-1)/(4x-3)
2y + 2xy' + 4y + 4xy' = 0 6y + 6xy' = 0 y' = -y/x
-17
that's impossible
This is not Calculus.y=7(Already solved)substiute y=7 into y=8xtherefore 7 = 8xtherefore x = 7/8
4xy+1=3y-7x 4xy-3y=-7x-1 y(4x-3)=-7x-1 y=(-7x-1)/(4x-3)
2y + 2xy' + 4y + 4xy' = 0 6y + 6xy' = 0 y' = -y/x
y=7+x =x=7-x
4xy = 4(3)(-7) = - 84
y= -4x-7 y=3x 3x= -4x-7 3x+4x=7 7x=7 x=1
-17
that's impossible
This is not Calculus.y=7(Already solved)substiute y=7 into y=8xtherefore 7 = 8xtherefore x = 7/8
5x+y=-7 3x+y=15 8=D
3/Y+7\Y=9 =>Y=10\9
just put in the numberssinze x = 3 and y = 2then(4*3*2) - (3) = 21
x=4 y=x+3 y=4+3 y=7
