Question

1000a+200b+30c+4d=3102​

Answer 1

Răspuns:

a = 2 ; b = 5 ; c = 3 ; d = 3

Explicație pas cu pas:

1000a+200b+30c+4d = 3102​

4d = 12 => d = 12:4 => d = 3

30c = 90 => c = 90:30 => c = 3

200b = 1000 => b = 1000:200 => b = 5

1000a = 2000 => a = 2000:1000 => a = 2

-----------------------

a = 2 ; b = 5 ; c = 3 ; d = 3 =>

1000 x 2 + 200 x 5 + 30 x 3 + 4 x 3 =

= 2000 + 1000 + 90 + 12 =

= 3000 +102 = 3102
