Xian and his cousin Kai both collect stamps. Xian has 56 stamps, and Kai has 80 stamps. The boys recently joined different stamp-collecting clubs. Xian's club will send him 12 new stamps per month. Kai's cllub will send him 8 new stamps per month. After how many months will Xian and Kai have the same number of stamps? How many stamps will each have?
They both will have 128 stamps in 6 months. Equation- 56+12x= 80+8x solution x=6 (in 6 months they will have same stamps) plug 6 into both equations to figure out how many stamps. 56+12*6=128 (xians equation) 80 +8*6= 128 (kais equation) Hope this helped!
