what is the ordered pair in y=2x+4 and 2x-y=6

Question

I do not have any more information.

Answer 1

o solve for y, we want to make sure that y is all by itself on one side of the equation. 

First, we subtract 2x from both sides. 

2x - 4y = 6 
becomes 
2x - 4y - 2x = 6 - 2x 
-4y = 6 - 2x 

Then, we divide both sides by -4. 

-4y/-4 = 6/-4 - 2x/-4 

Simplify.... 

y = 3/-2 - x/-2 

And correct for the negative signs. Remember that dividing a negative by a negative gives you a positive. 

y = -3/2 + x/2 

There you go.

Unfortunately, Kayla, you did not answer the question. It asked for an ordered pair, which would be in the form of (x, y). You are given two different equations, with the expectation that you can find a point of intersection, where the lines cross.

Also, where did you get 2x - 4y = 6? It doesn't appear in the problem statement.
