Problem on Solving for the Value of x by Cross Multiplication Method

Topic : Cross Multiplication Method

Problem : Solve For x by Cross Multiplication Method
(4x-3)/(2x) = (2x-4)/(x-2)
Solution :
(4x-3)/(2x) = (2x-4)/(x-2)
(4x-3)(x-2) = (2x-4)(2x)
4x²-8x-3x+6 = 4x²-8x
-4x²+8x = -4x²+8x
-3x+6 = 0
x = - 6/- 3
x = 2


Hope the Method will help you to Solve many Problems like this.
