Question

Determine o valor de x e y para que cada igualdade seja verdadeira.
(x + 1, y) = (8, 7)
(x – 3, y + 2) = (7, 4)
(x – 2, 9) = (3, y + 3)
(x, 10) = (6, y)

Answer 1

(x + 1, y) = (8, 7)
x=7 y=7
(7 + 1, 7) = (8, 7)
(8, 7) = (8, 7)


(x – 3, y + 2) = (7, 4)
x=10 y=2
(10 – 3, 2 + 2) = (7, 4)
(7, 4) = (7, 4)


(x – 2, 9) = (3, y + 3)
x=5 y=6
(5 – 2, 9) = (3, 6 + 3)
(3, 9) = (3, 9)


(x, 10) = (6, y)
x=6 y=10
(6, 10) = (6, 10)
