✔ 最佳答案
y = (4x-3) / (2x+1)y (2x+1) = 4x -3
2xy + y = 4x-3
y+3 = 4x - 2xy
y+3 = x (4-2y)
x = (y+3) / (4-2y)

y = (4x - 3)/(2x + 1)
y(2x + 1) = 4x - 3
2xy + y = 4x - 3
4x - 2xy = y + 3
x(4 - 2y) = (y + 3)
x = (y + 3)/(4 - 2y)
y(2x + 1) = 4x - 3
2xy + y = 4x - 3
4x - 2xy = y + 3
x(4 - 2y) = (y + 3)
x = (y + 3)/(4 - 2y)

y(2x+1)=4x-3
2xy+y=4x-3
2xy+y+3/4=x
x=2xy+y+3/4

2xy+y=4x-34x-2xy=y-3x(4-2y)=y-34-2y/y-3=x
2xy+y=4x-3
2xy+y+3/4=x
x=2xy+y+3/4
2006-10-22 23:22:07 補充：
2xy+y=4x-34x-2xy=y-3x(4-2y)=y-34-2y/y-3=x

y ( 2x+1) = 4x -3
2xy + y = 4x-3
4x-2xy = y+ 3
x ( 4-2y )=y+3
x= y+3 over 4-2y
2xy + y = 4x-3
4x-2xy = y+ 3
x ( 4-2y )=y+3
x= y+3 over 4-2y
