Answer:
Write a system of equations to model the situation. Add the equations to eliminate the y-term and then solve for x. Substitute the value for x into one of the original equations to find y. Check your answer by substituting x = 8 and y = 2 into the original system.

Answer:
Exactly one solution (unique) which is (0,0).
Step-by-step explanation:
Given, y=x, we can rewrite as x-y=0, now a1=1, b1=-1
y=2x, we can rewrite as 2x-y=0, now a1=2, b1=-1
So, a1/a2 not equal to b1/b2.
So, they have exactly one solution (unique) which is (0,0).
