Question

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

Answer 1

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

11xX-55=5xX+11

11xX-5xX=11+55

6xX=66

X=66:6=11

Answer 2

Ta có : 11.(x - 5) = 5x + 11

=> 11x - 55 = 5x + 11

=> 11x - 5x = 11 + 55

=> 6x = 66

=> x = 66 : 6 

=> x = 11

Answer 3

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

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

        \(11x-55=5x+11\)

        \(11x-5x=11+55\)

                     \(6x=66\)

                        \(x=11\)

Answer 4

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

=> 11xX - 11x5 = 5xX+11

=> 11xX - 55 = 5xX+11

=> 11x X= 5xX +11+55=5xX + 66

=> 6xX= 66( bớt cả 2 vế đi 5xX)

=>X= 66:6= 11

VẬY X=11

tk cho mình nha

mình hứa sẽ tk lại, ôk

cảm ưn

Answer 5

Ta có :

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

suy ra :

11x + 55 = 5x + 11

11x - 5x = 11 + 55

6x = 66

x = 66 : 6

x = 11
