Drex's and max's ages add up to 29.seven years ago drex was twice as old as max. find their present ages

There present ages are

Drex age = 17 years

Max age  =  12 years

Step-by-step explanation:

Given as ,

The sum of age of Drex and Max = 29 years

And seven years ago Drex was twice as old as max

So , Let the Age of Drex = D   and Max age = M

I.e (D - 7 ) = 2 (M - 7)

Or, D - 7 = 2M - 14

Or, 2M - D = 7

And Also D + M = 29  

So , from both equations

(2M - D ) + (D + M) = 29 +7

Or,  3M = 36

I.e M = = 12 years

∴ The Age of Drex = 29 - M

  The Age of Drex = 29 - 12 = 17 years

Hence there present ages are

The Age of Drex = 17 years

The Age of Max = 12 years     Answer
