Answer:
value of x is 3
Step-by-step explanation:
2x-1 / 5x-6 = 6x+2 / 15x-9
hence by cross multiplication
(2x-1)(15x-9) = (5x-6)(6x+2)
30x^2 -15x -18x +9 =30x^2 +10x -36x - 12
hence 30x^2 and 30x^2 get cancelled on both sides.
-33x + 9 = -26x - 12
9+12 = -26x +33x
21 = 7x
∴ x = 3
....hope you will understand what i tried to explain.
