Question

Tìm X biết 11x (X-6)=4 x X+11

Answer 1

\(11\left(x-6\right)=4x+11\Leftrightarrow11x-4x=11+66\Leftrightarrow7x=77\Leftrightarrow x=11\)

Answer 2

11(x-6)=4x+11

=>11x-4x=11+66

=>7x=77

=>x=77:7

=>x=11

vậy x=11

Answer 3

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
