Question

How many solutions does this system have?
Please explain too! :)
2x + 3 = y
6x = 9 - 3y

Answer 1

One solution, if you graph both lines the intersect once, so one solution :)

Answer 2

Both given equations solve to the same equation, thus there are infinite solutions. We can see this by solving both for x:

Y=-2x+3
y=-2x+3

Answer 3

I was always told to graph, like this
