Hay Mate

Let's Solve,

(3x+1)(x-1) = (5x-3)(2x-3)

=> 3x²-3x+x-1 = 10x²-15x-6x+9

=> 3x²-10x²-3x+15x+x+6x = 9+1

=> -7x²+12x+7x = 10

=> -7x²+19x = 10

=> 7x²-19x+10 = 0

=> 7x²-14x-5x +10 = 0

=> 7x(x-2) -5(x-2) =0

=> (7x-5) (x-2) = 0

(7x-5) = 0

7x-5 = 0

7x = 5

x = 5/7

or,

(x-2) =0

x -2 =0

x = 2

I hope it's help you
