**Five Number Summary**

It's not 6, Renee. You have to solve for x in the equation I made for you. (8+5+10+3+x)/5=6 (26+x)/5=6 26+x=30 x=?

Agreed, Kelly. Good for you. I think what Reiny was getting at is at the origin the point is (0,0) so it is possible. Not 100% positive though.

x+4y=-16 (1) 3x+2y=12 (2) Multiply (1) by -3 to get the x's to cancel -3x-12y=48 (3) 3x+2y=12 (2) Now add (3) and (2) together. -10y=60 Divide by -10. y=-6 Substitude y=-6 into equation (1) or (2) to solve for x.

L=laser tag, V=video games 3L+5V=17 (1) 4L+7V=23 (2) Since the question asks only about the video games, we want to eliminate the L's. We can do this by multiplying the first equation by 4 and the second equation by -3. 12L+20V=68 (3) -12L-21V=-69 (4) Add 3 and 4 together...
