Answer:

  (x, y) = (20, 449)

Step-by-step explanation:

When the equations are in this form, it is easiest to substitute one of the expressions for y into the other equation. That gives ...

  21.95x +10 = 22.45x

  10 = 0.50x . . . . . subtract 21.95x

  20 = x . . . . . . . . .multiply by 2

  y = 22.45x = 22.45·20 = 449
