what formula can be use to find Currently, Sam's coach is twice as old as Sam. When Sam started soccer 10 years ago, his coach was 3 times his age. How old is Sam now?..... i do NOT want the answer just the formula to find the answer
y = Sam's coach's age x = Sam's age y = 2x y - 10 = 3(x - 10)
hopefully that's a good enough starting point :) if not just ask
i have not the slightest idea except it can either be 20, 10, 30 or 15
do you have another starting point because i think thats to close to the finish line :)
