x%2B5%2Ay=3 Start with the given equation


Let's test the first solution (-12,3):


%28-12%29%2B5%2A%283%29=3 Plug in x=-12 and y=3


3=3 Simplify. Since the two sides of the equation are equal, this means (-12,3) is a solution to x%2B5%2Ay=3



-------Now lets test another solution-------



Let's test the second solution (3,0):


%283%29%2B5%2A%280%29=3 Plug in x=3 and y=0


3=3 Simplify. Since the two sides of the equation are equal, this means (3,0) is a solution to x%2B5%2Ay=3



-------Now lets test another solution-------



Let's test the third solution (-12,-3):


%28-12%29%2B5%2A%28-3%29=3 Plug in x=-12 and y=-3


-27=3 Simplify. Since the two sides of the equation are not equal, this means (-12,-3) is not a solution to x%2B5%2Ay=3



-------Now lets test another solution-------



Let's test the fourth solution (-22,5):


%28-22%29%2B5%2A%285%29=3 Plug in x=-22 and y=5


3=3 Simplify. Since the two sides of the equation are equal, this means (-22,5) is a solution to x%2B5%2Ay=3


==============================================================================
Answer:
So the following ordered pairs are solutions to x%2B5%2Ay=3

(-12,3), (3,0), and (-22,5)
