To solve the first equation, we need to isolate the y variable on one side of the equation:

11y - 7 = -22 + 5
Subtract 5y from both sides
6y - 7 = -2
Add 7 to both sides
6y = -1
Divide by 6
y = -15/
y = -2.5

To solve the second equation, we need to isolate the a variable on one side of the equation:

3a - 5 = 8a - 1
Subtract 3a from both sides
-5 = 5a - 1
Add 15 to both sides
10 = 5
Divide by 5
a = 2

Therefore, the solution to the first equation is y = -2.5 and the solution to the second equation is a = 2.
