Question

11.[x-6]=[4.x] +11

dấu chấm là dấu nhân 

Answer 1

\(11.\left(x-6\right)=\left(4.x\right)+11\)

\(11x-66=4x+11\)

\(11x-4x=11+66\)

\(7x=77\)

\(x=11\)

Answer 2

11.(x-6) = (4.x)+11

11.x - 66 = 4x + 11

=> 11.x - 4x = 11 + 66

7x = 77

x = 11

Answer 3

11. (x-6) = (4.x )+11

11.x - 66 = 4x + 11

=> 11.x - 4x = 11 + 66

7x=77

x=11

Answer 4

\(11\left(x-6\right)=4x+11\)

\(\Leftrightarrow11x-66=4x+11\)

\(\Leftrightarrow11x-4x=11+66\)

\(\Leftrightarrow7x=77\)

\(\Leftrightarrow x=77:7\)

\(\Leftrightarrow x=11\)

Vậy x=11
