Question

X x 27 + X x 30 + X x 43 = 210 500

Answer 1

\(27x+30x+43x=210500\)

\(100x=210500\)

\(x=210500:100\)

\(x=2105\)

vậy \(x=2105\)

Answer 2

= a x (27 + 30 + 43 )

= a x 100

= 210 500 : 100

= a = 2105

Answer 3

X x 27 + X x 30 + X x 43 = 210 500 . 

X x 100                            = 210 500 . 

X                                      = 210 500 : 100 . 

X                                      = 2105 . 

Answer 4

X x 27 + X x 30 + X x 43 = 210 500

=> X x (27 + 30 + 43) = 210 500

=> X x 100 = 210 500

=> X = 210500 : 100

     X = 2 105
