Asked by peter
please can you help me solve the following equations and please can you show your method. thanks
1) 4x+3/5x-6 = x-1/x-6
2) 4x-5/1-6x = x+10/x-6
thanks once again
1) 4x+3/5x-6 = x-1/x-6
2) 4x-5/1-6x = x+10/x-6

If I solve it the way you typed it .....
1. LCD is 5x, so multiply each term by 5x
20x^2 + 3x^2 - 30x = 5x^2 - 5 - 30x
etc
Somehow I have a feeling you meant
(4x+3)/(5x-6) = (x-1)/(x-6)
cross-multiply
5x^2 - 5x - 6x + 6 = 4x^2 - 24x + 3x - 18
x^2 + 10x + 24 = 0
(x+6)(x+4) = 0
x = -6 or x=-4
Do the second one the same way
