Answer:

z=-317

Step-by-step explanation:

1) Simplify 45 × 28  to  1260.

1260=19*83+z

2)  Simplify  19 × 83  to  1577.

1260=1577+z

3) Subtract 1577 from both sides.

1260-1577=z

4) Simplify  1260 - 1577  to −317.

-317=z

5) Switch sides.

z=-317

<u><em>Therefor, the answer is </em></u><u><em>z = -317.</em></u>
