Answer:

1722/31 or 55.55

Step-by-step explanation:

We need to write an equation.

-61( z - 56 ) = z - 28

-61z + 3416 = z - 28

-61z + 61z + 3416 = z + 61z - 28

3416 = 62z - 28

3416 + 28 = 62z - 28 + 28

3444 = 62z

3444/62 = 62z/62

3444/62 = z

Since 3444/62 isn't a whole number let's reduce

3444/2 = 1722        62/2 = 31

1722/31 is our reduced fraction

Plug it into a calculator 55.5483 but rounded to two decimal places is 55.55
