Answer:

y = 1

Explanation:

- 5 -(15y - 1) = 2(7y - 16) - y

1. Distribute

- 5 - 1(15y - 1) = 2(7y - 16) - y

- 5 - 15y + 1 = 14y - 32 - y

2. Add Like Terms

- 5 - 15y + 1 = 14y - 32 - y

- 5 - 15y + 1 = 14y - 33

- 5 - 15y + 1 = 14y - 33

- 4 - 15y = 14y - 33

3. Addition prop. of eq.

(- 4 + 4) - 15y = 14y (- 33 + 4)

- 15y = 14y - 29

4. Subtraction prop. of eq.

(- 15y - - 14y) = (14y - 14y) - 29

-29y = -29

5. Division prop. of eq.

(-29y/-29y) = (-29/-29)

y = 1
