Explanation:
to determine if the values of y are a solution to the equation, substitute the values of y into the left side and if equal to the right side then they are a solution.
y = 70
- 1 = 10 - 1 = 9 ≠ - 2 → NO
y = 56
- 1 = 8 - 1 = 7 ≠ - 2 → NO
y = - 7
- 1 = - 1 - 1 = - 2 → YES
y = 0
- 1 = 0 - 1 = - 1 ≠ - 2 → NO
