To solve these equations, we will distribute the multiplication and then combine like terms.

Equation 1: 9 - 3(7 - 5y) = -3
Simplify the equation: 9 - 21 + 15y = -3
Combine like terms: -12 + 15y = -3
Add 12 to both sides: 15y = 9
Divide by 15: y = 9/15 = 3/5

Equation 2: 9 - 2(3 - 6y) = -3
Simplify the equation: 9 - 6 + 12y = -3
Combine like terms: 3 + 12y = -3
Subtract 3 from both sides: 12y = -6
Divide by 12: y = -6/12 = -1/2

Therefore, the solution to the system of equations is y = 3/5 and y = -1/2.
