 Question 53993: I've been trying to figure out how to do this problem but I can't seem to get it right. The problem is... Solve the system using any algebraic method I tried the problem a couple of times but I still couldn't get the answer right. This is what I tried: and that cancelled out the y value and left me with 4x+4z=8. Then I combined that cancelled out the y value again and left 7x+7z=14 and from there I got stuck.
