Question

Determine whether the system has no one, or infinitely many solutions.

y = 2x + 6
y = -x - 3​

Answer 1

one

Explanation:

I am using substitution method:

2x+6=-x-3

subtract 6 from both sides

2x=-x-9

add x to both sides

3x=-9

divide by 3

x=-3

you can also graph this to see. I personally like using desmos.

Answer 2

One solution

Explanation:

I think its 1 solution but I could be wrong, I looked it up and it said one solution.
