Question 227962: 2x-3/x-4=5/x-4 I attempted to solve by cross multiplying. Could you please help me by explaining how to solve for x? The problem is 2x-3 over x-4=5 over x-4. Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! 2x-3/x-4=5/x-4
Cross multiply
(2x-3)*(x-4) = 5(x-4)
Divide by x-4
2x-3 = 5
2x = 8
x = 4
----------
The hard way:
2x^2 - 11x + 12 = 5x-20
2x^2 - 16x + 32 = 0
x^2 - 8x + 16 = 0
(x-4)^2 = 0
x = 4
