( 3x – 2 )( 4x – 3) - (2x - 3)( 4 + 6x ) = 4
(12x²-9x-8x+6)-(8x-12-18x+12x²)=4
12x²-17x+6+10x+12-12x²=4
-7x=-14
x=2
[tex](3x - 2)(4x - 3) - (2x - 3)(4 + 6x) = 4[/tex]
[tex](12 {x}^{2} - 9x - 8x + 6) - (8x + 12 {x}^{2} - 12 - 18x) = 4[/tex]
[tex]12 {x}^{2} - 9x - 8x + 6 - 8x - 12 {x}^{2} + 12 + 18x = 4[/tex]
[tex] - 7x + 6 + 12 = 4[/tex]
[tex] - 7x = 4 - 6 - 12[/tex]
[tex] - 7x = - 14[/tex]
[tex]x = 2[/tex]
