x = 12, TV = 11

x = 11, TV = 10

x = 15, TV = 14

x = 18, TV = 17

Notice the little congrunet marks on the segments with x. That means that are so equal. So First solve  2x+1 = x+7 to find the value of x. Then since those are congruent the segments with are being proportional are going to be congruent also. So solve 3y-8 = y+5 to find the value of y. 

x = 9, y = 7.5

x = 6, y = 6.5

x = 12, y = 8.5

x = 8, y = 6.5

This turns out to be a quadractic function. It will be easier to plug the answer choices back in up into the figure and see which answer makes sense.

This one is very similar to problem #4. 

x = 5, y = 2

x = 9, y = 3

x = 8, y = 2

x = 5, y = 6
