Solve the following system of equations by using substitution.

1) Solve for y by substituting x = -6y - 11 into the equation 5x + 6y = 23
 
    5 (-6y - 11) + 6y = 23
 
2) Take the value of y and plug it into x = -6y - 11 to solve for x
 
        x = -6 y - 11 
5 x + 6 y = 23
 
Solution: (   1   ,    2   )
