Answer:
9,21
Step-by-step explanation:
Check each pair separately
(-12, 24) - if x=-12, then y = 24
let us check with substituting the value of x in the equation and finding y
y = -12 + 12 = 0
if x = -12, y = 0, which does not correspond to your pair
Check the next ones the same way
(12,24)
x = 12
y = 12 + 12 = 24
(12,24) - a solution
(0,-12)
x = 0
y = 0 + 12 = 12, not -12
(-12,0)
x = -12
y = -12 + 12 = 0
true
(-12,0) - a solution
So, we have to pairs that are the solutions for the given equation
(12,24) and (-12,0)
