Three numbers are chosen at random. the middle number is 5 more than the smallest number. the largest number is two times the smallest number. the sum of the 3 numbers is 53. what is the smallest number?

the answer is su.k.my? ? co.kc

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
