Answer:
$16.00
Step-by-step explanation:
6 wood chairs are 444 which is 74.00 a piece
8 metal chairs are 720 which is 90.00 a piece
90-74= 16
The metal chairs are $16.00 more
Honestly photo math is the way to go but I got r= 17/13
So when you're solving for x here and distribute 8 on the right side, it would look like this:

Now in order to solve for x, we know we have to get all the x's on one side of the equal sign. Let's get all our x's to the left side. Since the right side has a positive 8x, you need to subtract 8x on the right. But whatever you do to one side you must do to the other. So since we are subtracting 8x on the right, we need to do that on the left.
But we can't! Since both sides will cancel out to zero before x can be solved.
Therefore the answer is 0.
Hope that helps!
