for x<5
for x>5

for x<3/2
for x>3/2

So we need to look for solutions for x in three intervals: (-infinity,3/2), (3/2,5), and (5, infinity).

(1) (-infinity,3/2)






x=0 is in the interval we are working in, so x=0 is a solution -- or, rather, (x,y)=(0,5) is a solution.

(2) (3/2,5)







x=2 is also in the interval we are working in, so (x,y)=(2,3) is a solution.

(3) (5,infinity)






x=-4 is not in the interval we are working in, so this is not another solution.

ANSWER: (x,y)=(0,5) and (x,y)=(2,3)

A graph, showing the graphs of the two absolute value functions intersecting at (0,5) and (2,3)....
