Solve x plus 7 divided by x minus 2 equals x plus 4 divided by x minus 3?
x + 7 / x - 2 = x + 4 / x - 3(times both sides by x - 3 and x - 2)(x + 7)(x - 3) = (x + 4)(x - 2)x2 + 7x - 3x - 21 = x2 + 4x - 2x - 8x2 + 4x - 21 = x2 + 2x - 8(- x2 from both sides)4x - 21 = 2x - 8(- 2x from both sides)2x - 21 = -8(+ 21 on both sides)2x = 13(divide both sides by 2)x = 6.5
