Question

386×62+386×a=38600; Vậy a=

Answer 1

386.62+386.a=38600

386.(62+a)=38600

62+a=100

a=38

Answer 2

     \(386\times62+386\times a\)\(=38600\)

\(\Leftrightarrow386\times\left(62+a\right)=38600\)

\(\Leftrightarrow62+a=38600:386\)

\(\Leftrightarrow62+a=100\)

\(\Rightarrow a=100-62\)

     \(a=38\)

Answer 3

386 x 62 + 386 x a = 38600

( 62 + a ) x 386 = 38600

  62 + a = 38600 : 386

  62 + a = 100

  a = 100 - 62

  a = 38

Vậy a = 38

Answer 4

386x62+386xa=38600

(62+a)x386=38600
