Question

a 64 . x + 34 . x = 1930

b 119 . x + 81 . x = 9751000

Answer 1

a) 64.x + 34.x = 1930

=> (64 + 34).x = 1930

=> 98.x = 1930

=> x = 1930 : 98 = 965/49

b) 119.x + 81.x = 9751000

=> (119 + 81).x = 9751000

=> 200.x = 9751000

=> x = 9751000 : 200 = 48755

Answer 2

a) 64x + 34x = 1930

<=> 98x = 1930

<=> x= \(\frac{965}{49}\)

b) 119x + 81 x = 9751000

<=> 200x = 9751000

<=> x= 48755

Answer 3

          Bài làm :

a) 64.x + 34.x = 1930

<=> (64 + 34).x = 1930

<=> 98.x = 1930

<=> x = 1930 / 98 = 965/49

b) 119.x + 81.x = 9751000

<=> (119 + 81).x = 9751000

<=> 200.x = 9751000

<=> x = 9751000 / 200 = 48755
