Okay, let's try and solve the system of equations by using elimination. How many times does the second equation go in the first?
i dont know
Put the equation side by side one another. What do you have to multiply with x to turn into 2x? What do you have to multiply with y to get 2y and what do you have to multiply with 9 to get 18? 2x + 2y = 18 x + y = 9
Multiply the second equation by 2 then. 2(x + y = 9) It'll equal the first equation. If the second equation and the first equation are equal, what does that mean?
i dont know
It means that they're the same line.
I'm willing to help if you're at least willing to try.
but i don't get what the answer will be
What do same lines have? Infinite solutions, no solution, or just one solution?
just 1 solution
Nope. Try again.
No. They have infinite solutions. Every single point is the same.
