Answer:

no

Step-by-step explanation:

using the values of the ordered pair in the first equating we get :

2 = 3×5 - 13 = 15 - 13 = 2

that fits.

but when using them in the second equation we get :

4×5 - 3×2 = 17

20 - 6 = 17

14 = 17

and that is wrong.

that means the point (5, 2) is not on the second line, so the point cannot be the crossing point (= solution, where both equations deliver the same result) of both lines.

FYI

we would solve the system by using the first equality directly in the second equation :

4x - 3(3x - 13) = 17

4x - 9x + 39 = 17

-5x = - 22

5x = 22

x = 22/5 = 4.4

and y is then

y = 3×4.4 - 13 = 13.2 - 13 = 0.2

the actual solution of the system is therefore

(4.4, 0.2)
