You would not subtract 2 from 6 because they are not like terms that you can combine - one of them contains a variable.
You would solve this equation like so:
6z - 2 = 0 The given equation
6z = 2 Add 2 to both sides
z = 1/3 Divide both sides by 6
Answer:
z = 1/3

Step-by-step explanation:
When two ferries work together, they transport a day's cargo in 7 hours
The speed proportion or ratio of larger ferry to smaller ferry is given as 3 : 1
The sum of the ratio = 4 (3 + 1)
This means that it will take the smaller ferry = 7 x 4 hours to work alone = 28 hours, since the larger ferry is faster by 3.
Therefore, when larger ferry works alone, it will take it (7 x 4)/3 = 9.33 hours.
9.33 hours = 9 hours, 20 minutes.
