Question

Tìm x 

812 × X + 188 × X = 10000

 

Answer 1

1000 x X = 10000

X = 10

Answer 2

812 × X + 188 × X = 10000

X ( 812 + 188 ) = 10000

X . 1000 = 10000

X = 10000 : 1000

X = 10

Answer 3

Ta có:

\(812\times x+188\times x=10000\)

\(\Leftrightarrow x\times\left(812+188\right)=10000\)

\(\Leftrightarrow x\times1000=10000\)

\(\Leftrightarrow x=10\)

Answer 4

  812 × X + 188 × X = 10000

 =X x (812 + 188) = 10000

=X x 1000 = 10000

=10000:1000

=10

Chúc bn học tốt nha
