Question 77151: I would like you to help me. Please tell me if I'm doing this right, if I am what would the next step be. The directions say solve the equation by cross multiplying.
x+3/x+1 = x+4/x+5
(x+3)*(x-5) = (x+1)*(x+4)
x^2+3x-5x-15 = x^2-x+4x-4
x^2-5x-15 = x^2+3x-4
Any help would be greatly appricated.
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
(x+3)/(x+1) = (x+4)/(x+5)
(x+3)*(x+5) = (x+1)*(x+4)
x^2+3x+5x+15 = x^2+x+4x+4
x^2+8x+15 = x^2+5x+4
3x+11=0
x=-11/3
==========
