=
2x−3
3x−7
(x + 3)(2x - 3) = (3x - 7)(x + 2)(x+3)(2x−3)=(3x−7)(x+2)
2 {x}^{2} - 3x + 6x - 9 = 3 {x}^{2} + 6x - 7x - 142x

−3x+6x−9=3x

+6x−7x−14
2 {x}^{2} - 3 {x}^{2} + 3x - 9 = - x - 142x
2
−3x

+3x−9=−x−14
- {x}^{2} + 3x - 9 + x + 14 = 0−x
2
+3x−9+x+14=0
- {x}^{2} + 4x + 5 = 0−x
2
+4x+5=0
- ( {x}^{2} - 4x - 5) = 0−(x
2
−4x−5)=0
{x}^{2} - 4x - 5 = 0x
2
−4x−5=0
{x}^{2} - (5 - 1)x - 5 = 0x
2
−(5−1)x−5=0
{x}^{2} - 5x + x - 5 = 0x
2
−5x+x−5=0
x(x - 5) + 1(x - 5) = 0x(x−5)+1(x−5)=0
(x - 5)(x + 1) = 0(x−5)(x+1)=0
Either, x-5=0 => x = 5
Or, x+1=0 => x = -1.
The values of x are 5 and -1
