It will be greatly appreciated if you can solve the question and show steps as well. THANK YOU!Answer by ankor@dixie-net.com(15652)   (Show Source): You can put this solution on YOUR website!Let b = B's present age Let m = M's present age : Write an equation for each statement: : "Betty is now three times as old as mike," b = 3m : "but in five years she will be only twice as old as mike." (5yrs added to both ages) b + 5 = 2(m + 5) b + 5 = 2m + 10 b = 2m + 10 - 5 b = 2m + 5 from the 1st statement, we know b = 3m, replace b with 3m in the above equation 3m = 2m + 5 3m - 2m = 5 m = 5 yrs is M's present age : : To check our solution, find B's age 3(5)=15 is B's present age Use these values in the statement: "in five years she will be only twice as old as mike. " 15 + 5 = 2(5+5)confirms our solution of m=5
