Question

X x 4 + X x 5 =27

Answer 1

x=3

quá dễ

Answer 2

X x 4 + X x 5 =27

X x ( 4 + 5 ) = 27

X x 9 = 27

X = 27 : 9

X = 3

Answer 3

\(x\times4+x\times5=x\times9=27\)

\(x=27:9=3\)

Answer 4

X x 4 + X x 5 = 27

X x ( 4 + 5)    = 27

X x  9           = 27

X                 = 27 : 9 (TTS)

X                 = 3

Answer 5

X x 4 + X x 5 =27

 X x ( 4 + 5 ) = 27

X x 9 = 27

   X = 27 : 9

   X=3

  

Answer 6

X x 4 + X x 5 =27

                    X x ( 4 + 5 ) =27

                              X x 9 =27

                                    X =27:9

                                     X=3

ấn đúng cho mình nha

Answer 7

=X x 9 = 27

=X=3

Answer 8

Xx5+Xx4=27

Xx(5+4)=27

Xx9=27

X=27:9

X=3

 

Answer 9

X x 4 + X x 5 = 27

X x ( 4 + 5 )   = 27

X x 9             = 27

X                   = 27 : 3

X                   = 9

Answer 10

\(x\times4+x\times5=27\)

     \(x\times\left(4+5\right)=27\)

                  \(x\times9=27\)

                           \(x=\frac{27}{9}\)

\(x=3\)
