minus y both sides in first equation
x-y=16
add that to 2nd equation

x-y=16
2x+y=5 +
3x+0y=21

3x=21
divide both sides by 3
x=7
the x coordinate is x=3

for the y axis equation, plug in the x equation so it looks like this
y+2(y+16)=5
Redistribute: y+2y+32=5.
Simplify: y= -13.5
Plug the y value into the x=equation: x= -13.5+16
Simplify: x=2.5
