`2(5x-8)-3(4x-5)=4(3x-4)+11`
`=> 10x-16-(12x-15)=12x-16+11`
`=> 10x-16-12x+15=12x-5`
`=> -2x-1=12x-5`
`=> 12x+2x=5-1`
`=> 14x=4`
`=> x=2/7`
VT: 2( 5x - 8 ) - 3( 4x - 5 )= 10x - 16 - 12x + 15 = - 2x - 1
VP: 4( 3x - 4 ) + 11 = 12x -16 + 11 = 12x - 5
ta có VT = VP suy ra
- 2x - 1 = 12x - 5 \(\Rightarrow14x=4\Rightarrow x=\dfrac{2}{7}\)
