Question

Pls Help

Answer 1

you're going to want to look for two equations that are equivalent. do you have any ideas?

Answer 2

In order for a system of equations to have infinite solutions, the equations MUST BE THE SAME.
You must set the equations into y=mx + b form to know if they are the same. Let's do this for A. For the first equation, we add 4x to both sides and then divide by 6 to get:
y=2/3x+ 10/3
For the second equation in A, you subtract 4x from both sides and then divide by -3 to get:
y=4/3x + 2/3
They are NOT the same equation, so A cannot be our right answer.
Let's try B. For the first equation, add 2x to both sides and then divide by 4 to get:
y=1/2x +4.5
For the second equation, you subtract 4x from both sides and then divide by -8. You get:
y=1/2x+4.5
As you can see, they ARE the same equation. This means they have infinitely many solutions, since they are the same ''line'' and a line goes on forever. If you have any more questions, please let me know. I will be happy to explain this further. :D
