    Work: Find the solution of equation 3/x-1 = 0 .
    Question type: Equation
    Solution:Original question:

3

÷

x

−

1

=

0

Multiply both sides of the equation by:

x

3

−

1

x

=

0

    Transposition :

-

1

x

=

0

−

3

    i.e.

-

x

=

0

−

3

    Combine the items on the right of the equation:

-

x

=

-

3

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :

3

=

x

    If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :

x

=

3

    This is the solution of the equation.
    This is the solution of the equation.
