Answer:
One
Step-by-step explanation:
It is given that,
y = 3x-5 ....(1)
y = -x+4 .....(2)
We can solve the above equations using substitution method. Put the value of y from equation (1) to equation (2) such that,

Put the value of x in equation (1) we get :

It means that the value of x is
and the value of y is
. Hence, the given equations has only one solution.
