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
