To solve this system, we can use substitution.


x + 6y = 61

x = 61 - 6y


Now we substitute into the other equation.


4 (61 - 6y) - 5y = -17

244 - 24y - 5y = -17

244 -29y = -17

29y = 261

y = 9


Now we find x.


x + 6 (9) = 61

x + 54 = 61

x = 7


That means the solution to this system is (7, 9)
