I will use the Substitution Method: Method 1 (Substitution) : x = first number y = second number x + y = 50                  Equation 1 x = 2y - 43                 Equation 2 Substituting Equation 2 into Equation 1: 2y - 43 + y = 50 2y + y = 93                          Add 43 to each side. 3y = 93                                Addition. y = 31                                  Divide each side by 3. Substituting value of y into Equation 1: x + 31 = 50 x = 19                                  Subtract 31 from each side. Answer: x = 19 and y = 31
