Answer:
x = -1, y = 1
Step-by-step explanation:
Multiply the top equation by 2:
Leaving the bottom equation unchanged, add the two resulting equations to eliminate y, obtaining:
Solve this for x, and then substitute this value of x into the bottom equation. Finally, solve for y.
Answer:
this equation has exactly 1 solution
