Yes. For example #(x,y)=(1,3)# is a solution to this equation located in the first quadrant.

Explanation:

If an equation in #x# and #y# has a solution for which both #x > 0# and # #y > 0#
then it is at least partially contained within the first quadrant.

For all coordinates #(x,y)# in the first quadrant #x > 0# and #y > 0#
