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

`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`

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

11(x-6)=4x+11

=>11x-4x=11+66

=>7x=77

=>x=77:7

=>x=11

vậy x=11

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

11x-66=4x+11

11x-4x=66+11

7x=77

x=77:7

x=11

 Vậy x=11

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

=>11x-66=4x+11

=>11x-4x=66+11

=>7x=77=>x=11

Toán khó vậy Việt !!!

11x(X-5)=5xX+11

11xX-55=5xX+11

11xX-5xX=11+55

6xX=66

X=66:6=11

Ta có : 11.(x - 5) = 5x + 11

=> 11x - 55 = 5x + 11

=> 11x - 5x = 11 + 55

=> 6x = 66

=> x = 66 : 6 

=> x = 11

\(11\times\left(x-5\right)=5\times x+11\)

\(11x-11\times5=5x+11\)

        \(11x-55=5x+11\)

        \(11x-5x=11+55\)

                     \(6x=66\)

                        \(x=11\)

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

\(\Rightarrow11x-66-4x=11\)

\(7x=11+66=77\Rightarrow x=11\)

11.(x-6) - 4.x=11 (chương trình thcs nhân là chấm nha)

11x-66-4x=11 (lấy 11 nhân vs x và 6)

7x=11+66   (chuyển vế là dc nha)

7x=77

x=11

11X-66-4X=11

=>7X-66=11

=>7X=77=>X=11

X là nhân à?

6/11X 3/7 + 3/7 X 5/11

=\(\dfrac{6x3}{11x7}+\dfrac{3x5}{7x11}=\dfrac{18}{77}+\dfrac{15}{77}=\dfrac{33}{77}\)

Kết quả là 33/77 em nhé! :)

\(\dfrac{6}{11}\) . \(\dfrac{3}{7}\) + \(\dfrac{3}{7}\) . \(\dfrac{5}{11}\)

= ( \(\dfrac{6}{11}\) + \(\dfrac{5}{11}\) ) \(\dfrac{3}{7}\)

= 1 . \(\dfrac{3}{7}\) = \(\dfrac{3}{7}\)

-1/4               

= -0,25
