if you are solving systems of equations and your solving for y how do you get rid of the x
What is/are the equation/equations? You can use substitution, elimination, and one that I can't remember... I think there were three ways, weren't there?
um.. ya i think there is three burt idk we just started doing this but the equations are y= -3/2x +3, and y= -x +6
Let's try doing substitution.
Since y equals both -3/2x+3 and -x+6, let's set them equal to each other.
Set the equations equal to each other.
-3/2 x+3=-x+6
Add 3/2 x to both sides.
3=1/2x+6
Subtract 6 from both sides.
1/2x=-3
Multiply by 2 on both sides.
x=-6
Check your answer:
-3/2(-6)+3=-(-6)+6
9+3=6+6
12=12 The answer is correct!
