The perimeter of a triangle is 26 centimeters. three times the length of the longest side minus the length of the shortest side is 37 centimeters. the sum of the length of the longest side and twice the sum of both the other side lengths is 38 centimeters. find the side lengths.

answer:

step-by-step explanation:

let's say x is longest side, y is shortest side and z is the other side. so we have some equations such that

(by the first sentence)

(by the second sentence)

  (by the third sentence)

by the second equation, we have   and if we use it in the first equation, then  . so 

since  , if we use it in the third equation the we have   then 

therefore 

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
