y =
Explanation:
I'd say for this one, I would use the elimination method. I'm not too good at formatting, but I'll give this my best shot.
Set it up like this:
4x - y = -1
6x - 4y= 3
Now, you want to get rid of one of the variables. Multiply (4x-y=-1) by -4. Now you have:
-16x + 4y = 4
6x - 4y = 3
Cancel out the 4y and -4y and add the rest of the similar terms. You're left with
-10x = 7
Divide both sides by -10 so you have just x.
x =
Now, plug x back into one of the equations. You can do either, but for this one I'll do the first one.
4(
4(
So...
Move the
-y =
Divide both sides by -1.
y =
Your answer is:
x =
y =
