Question

11x ( x-6) = 4 x X + 11 nhanh ạ:33

Answer 1

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

Answer 2

`1xx(x-6)=4xx x+11`

`11 xx x-11 xx 6=4xx x+11`

`11×x−66=4×x+11`

`11×x−4×x=11+66`

`(11−4)×x=77`

`7×x=77`

`x=11`

Vậy `x=11`
