Solve the given equation.

45
.
28
=
19
.
83
+
z

Answer 1

1260 = 1577+ z
-317=z

Answer 2

`z=-317`

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`

Therefor, the answer is z = -317.
