Question

2014 × a + 2014 × 79= 201400

 

Answer 1

2014.a+2014.79=201400

<=> 2014.(a+79)=201400

<=>a+79=100

<=>a=21

Answer 2

2014 x a + 2014 x 79 = 201400

( a + 79 ) x 2014 = 201400

  a + 79 = 201400 : 2014

  a + 79 = 100

  a = 100 - 79

  a = 21

Vậy a = 21

Answer 3

2014 * (a + 79) = 201400

a + 79 = 201400 : 2014

a + 79 = 100

a = 100 - 79

a = 21
