(x - 1)/(2x + 3) = y + 4
x - 1 = (y + 4)(2x + 3)
x - 1 = 2xy + 3y + 8x + 12
x - 2xy - 8x = 3y + 12 + 1
-7x - 2xy = 3y + 13
-x(7 + 2y) = 3y + 13
-x = (3y + 13)/(7 + 2y)
-x = (3y + 10.5 + 2.5)/(7 + 2y)
-x = (3/2)(2y + 7)/(7 + 2y) + 2.5/(2y + 7)
-x = 3/2 + 5 / (2(2y + 7))
x = - 3/2 - 5/(2(2y + 7))
x - 1 = (y + 4)(2x + 3)
x - 1 = 2xy + 3y + 8x + 12
x - 2xy - 8x = 3y + 12 + 1
-7x - 2xy = 3y + 13
-x(7 + 2y) = 3y + 13
-x = (3y + 13)/(7 + 2y)
-x = (3y + 10.5 + 2.5)/(7 + 2y)
-x = (3/2)(2y + 7)/(7 + 2y) + 2.5/(2y + 7)
-x = 3/2 + 5 / (2(2y + 7))
x = - 3/2 - 5/(2(2y + 7))
