The question is actually
“x^x + y^y = 31\nnx + y = 5”
not,
“x^x + y^y = 3\nnx + y = 5\”
The best way to solve this is graphically,
Table “x^x + y^y = 31\”
“x|y\n0|3.04\n1|3.04\n2|3\n3|0\”
Table “x + y = 5”
“x|y\n0|5\n1|4\n2|3\n3|2\”
The points of intersection are (2,3) and (3,2)
“therefore” “x=2” or “3”
“y=3” or “2”
