Answer:

(x, y) = (20, 449)

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
