Drex's and Max's ages add up to 29.Seven years ago Drex was twice as old as Max. Find their present ages​

Answer:There present ages areDrex age = 17 yearsMax age  =  12 yearsStep-by-step explanation:Given as ,The sum of age of Drex and Max = 29 yearsAnd seven years ago Drex was twice as old as maxSo , Let the Age of Drex = D   and Max age = MI.e (D - 7 ) = 2 (M - 7)Or, D - 7 = 2M - 14Or, 2M - D = 7And Also D + M = 29  So , from both equations (2M - D ) + (D + M) = 29 +7 Or,  3M = 36I.e M = [tex]\frac{36}{3}[/tex] = 12 years∴ The Age of Drex = 29 - M   The Age of Drex = 29 - 12 = 17 yearsHence there present ages areThe Age of Drex = 17 yearsThe Age of Max = 12 years     Answer
