Answer:
Infinitely many solutions.
Step-by-step explanation:
Given:
-5X +6y=12 .........eq 1
Y=5/6x+2 ..........eq 2
--------------------------------------------------------------------------
-5X +6y=12
6y = 12 + 5x .......eq 3
( Y=5/6x+2 ) * 6
6Y = 5X + 12 ...........eq 4
Using equation 3 and 4:
6y = 12 + 5x
6Y = 5X + 12
...............................
0
They are equal and cancels out. Therefore Infinitely many solutions.
