(3,0.5)
Step-by-step explanation:
The given system has equations:

Let us multiply the second equation by 4 and the first equation by 10.

We add both new equations to get:

Put x=3 into the first equation and solve for y.

The point of intersection is the solution to the system of equation which is (3,0.5)
3! =3 x 2 x 1 = 6
Y!= Y x (y-1) x ... x 1=
