At the animal shelter there are 56 more dogs than cats. If the total number of animals is 200 how many of each type are in the shelter?
dogs + cats = 200Â Â Â Â eq IÂ
dogs = 56 + cats     eq II
replace dogs in eq I
(56 + cats) + cats = 200 eq with one variable
56 + 2c = 200Â
2c = 200 - 56Â
2c = 144 /divided 2
cats= 72
dogs = 56 + cats = 56 + 72 = 128
dogs = 126
