( 3х + 4 ) ( 4х - 3 ) - 3 = ( 2х + 5 ) ( 6х - 7 )

Question

( 3х + 4 ) ( 4х - 3 ) - 3 = ( 2х + 5 ) ( 6х - 7 )

Answer 1

12х-9х+16х-12=12х-14х+30х-35
12х-12х-9х+16х+14х-30х=12-35
21х=-23
х=-23/21

Answer 2

( 3х + 4 ) ( 4х - 3 ) - 3 = ( 2х + 5 ) ( 6х - 7 )
12x²+16x-9x-12-3=12x²-14x+30x-35
7x-15=16x-35
20=9x
x=20/9=2 и 2/9
