The equation is 0.3x = –4.5.

Apply division property of equality: If a = b then .

        (Divide each side by 0.3) \ \

                (Cancel common terms)

x = –15                      (Divide: )

Check:

To check the solution, substitute x = –15 in original equation.

–4.5 = (0.3)(–15)

–4.5 = –4.5                 (Multiply: )

The statement is true.

The value of x = –15.
