−

47 1000

    Combine the items on the right of the equation:

1047 1000

y

=

63 1000

    The coefficient of the unknown number is reduced to 1 :

y

=

63 1000

÷

1047 1000

=

1 349

    We obtained :

y

=

21 349

    This is the solution of the equation.

    Convert the result to decimal form :

y

=
