Question

X x 62 +X x 48 = 4200

Answer 1

X x 62 +X x 48 = 4200

=> X x (62+48)=4200

=> X x 110=4200

=> X=4200:110

=> X=\(\frac{420}{11}\)

Answer 2

Xx62+Xx48 = 4200

Xx(62+48)=4200

Xx110=4200

X=4200:110

X=38(18)

Answer 3

X×62+X×48=4200

X×(62+48)=4200

X×110=4200

X =4200:110

X=\(\frac{420}{11}\)

Answer 4

       Xx62+Xx48 = 4200

<=> Xx(62+48)   = 4200

<=> Xx110         = 4200

<=> X                = 4200 : 110

<=> X                = 420/11

Answer 5

\(Xx62+Xx48=4200\)

\(Xx\left(62+48\right)=4200\)

\(Xx110=4200\)

\(X=4200:110\)

\(X=\frac{4200}{110}\)( Phép này bị dư bạn ạ )

Answer 6

\(x\times62+x\times48=4200\)

\(\Rightarrow x\times\left(62+48\right)=4200\)

\(\Rightarrow x\times110=4200\)

\(\Rightarrow x=\frac{420}{11}\)

Answer 7

x * 62 + x * 48 = 4200

x * ( 62 + 48 ) = 4200

x * 110 = 4200

x = 4200 : 110 

x = \(\frac{420}{11}\)

Chúc bạn học tốt!

Answer 8

X x 62 + X x 48 = 4200

X x ( 62 + 48 ) = 4200

          X x 110 = 4200

                  X = 4200 : 110

                  X =\(\frac{420}{11}\)
