You're on the right track!

You've already gotten to the part :

5x = 15

Just continue.

x = 15/5 = 3

The x-coordinate of P is 3.

Next, sub x = 3 into either equation :

y = 2x + 2

OR

y = -3x + 17


For the former,

y = 2(3) + 2
y = 6 + 2
y = 8

For the latter,

y = -3(3) + 17
y = -9 + 17
y = 8


So the y-coordinate of P is 8


∴ P(3,8)
