Answer:
p(4 , 2)
Step-by-step explanation:
x + y = 6
x = y +2
we clear the and in both functions
x + y = 6 x = y +2
y = -x + 6 y = x -2
Then we match what is the same and in both functions
x -2 = -x + 6
x + x = 6 + 2
2x = 8
x = 8/2
x = 4
Finally we replace the value obtained from x in any of the 2 functions and give us the value of y
x + y = 6
4 + y = 6
y = 6 - 4
y = 2
p(4 , 2)
