If yes, find the formula for the inverse. f(x) = (5x+4)/(7x+6) I have listed it as a one-to-one and have written the following: Changed f(x) to "y" y =(5x+4)/(7x+6) Then substituted "x" for "y" to get x = (5y+4)/(7y+6) My problem is that I don't know how to write the inverse. Please help.Answer by scott8148(6628)   (Show Source): You can put this solution on YOUR website!solve for y multiplying by 7y+6 __ 7xy+6x=5y+4 __ subtracting 6x+5y __ 7xy-5y=4-6x factoring __ y(7x-5)=4-6x __ dividing by 7x-5 __ y=(4-6x)/(7x-5) __ this is the inverse
