Homework Help: MATH

Posted by drwls on Wednesday, January 17, 2007 at 7:52pm.

24/(x+1) + 12/(4-x) = 14
Multiply both sides by (4-x)(x+1)
24(4-x) + 12(x+1) = 14(4-x)(x+1)
96 - 12x + 12 = -14(x^2 -3x -4)
= -14x^2 +42 x +56
Combine terms and solve for x.

sorry guys, here's another.I'm not the greatest at math but i do know some...
