\(11\left(x-6\right)=4x+11\Leftrightarrow11x-4x=11+66\Leftrightarrow7x=77\Leftrightarrow x=11\)
11(x-6)=4x+11
=>11x-4x=11+66
=>7x=77
=>x=77:7
=>x=11
vậy x=11
11 x (X-6)=4 x X +11 => 11 x X - 11 x 6=4 x X +11 => 11 x X - 66 = 4 x X+11 => 11 x X - 4 x X = 11+66 => (11-4) x X = 77 => 7 x X=77 => X=77:7 => X=11
