Determine x e y para que cada uma das igualdades seja verdadeira:
a) (x, y)=(8, -6)
b) (6, y)=(x, 0)
c) (x,-4)=(-3, y)
d) (2x, -5)=(8, y)
e) (x, y+2)=(8, y)
f) (3x, 2y)=(-12, -6)
g) (x-y, 5)=(0, y)
h) (x+1, y-1)=(3, 7)
i) (x-2, 7-y)=(-2, 6)
j) (3x+2, 2y-6)=(2x-1, y+2)
k) (5+3, 3y-2)=(3x-7, y+12)
l) (2x-10, 2x-5)=(6-2x, 3-2y)
m) (7x-10, 5y-7)=(2x+15, 11-3y)
n) (2x-2, 3y+2)=(x+5, 2y+9)
