Question 122442
x - 5y = 2
by substitution, x = 2 + 5y

Use in 2nd equation 11x + 13y = 22
                    11 (2 + 5y) + 13y = 22
                     22 + 55y + 13y = 22
                          68y = 22 - 22
                          68y = 0
                            y = 0

If y = 0
  x - 5y = 2
  x - 5(0) = 2
  x - 0 = 2
  x = 2

Therefore x = 2, and y = 0
