Question 1137349
.
<pre>
Let x be the Buddy age now.


Then Mark is (x+2) years old.


Then the condition states


(x+2) + 1 = 2(x+1).


Simplify and solve


x + 3 = 2x + 2

3 - 2  = 2x - x.

1 = x


<U>ANSWER</U>.  Buddy is 1 years old.  Mark is 1+2 = 3 years old.


<U>CHECK</U>.   In  a year  B= 2,   M = 3+1 = 4,  and  4 is twice as 2.   ! Correct !
