Answer:
1. No solutions
2. No solutions
3. Infinitely many solutions
Step-by-step explanation:
If a system is conflicting, like:
2y + x = 3
2y + x = 10
there are no solutions, because x can only have one value. In your question, it says
-10x + 18y = 5
-10x + 18y = 4
Which does the equation equal, 5 or 4? There are no solutions.
If a system has two equal equations, like:
2 + x = y
4 + 2x = 2y
there are infinitely many solutions because x could equal any number (an infinite amount of numbers) and the equation would still work.
In your question, it says:
-10x + 18y = 4
-5x + 9y = 2
If you multiply the bottom equation by 2, you'll find that they are the same.
