-2x-4y=1 12y=-6x-3

I have to find the solutions, or no solution, or infinite solutions to these two equations.

4 answers

the two equations are

2x+4y = -1
6x+12y = -3

multiply the top equation by 3 to get
6x+12y = -3

They are the same equation. So, what does that mean?
-2x-4y = 1
6x + 12y = -3

I just rearranged the second equation.

Multiply the top equation by 3 and then add the two equations together.

You will get 0 = 0 which means there are an infinite number of solutions. This happens any time you get a true equation. What you will find is that any x, y values that makes the first equation true will also work in the second equation.

If you got 0 = -3 then this would be false and indicate that there are no solutions.
It’s not right ok
idk
