the perimeter of a triangle is 69 cm. side a is 5 cm shorter than side b. side c is twice as long as side a. find the length of each side. i need to know how to do it in 2 equations.  

equations:

a = b-5

c = 2a

a + b + c = 69

i actually have a suggestion instead of an answer, how about next time instead of spending the time to time up the question you take that time and try to figure something out for yourself, do you understand?

explanation:

leave a 5 star and a and brainliest answer if you understand, hope this betters you day, or not i don't really care either way. xd
