Answer:
The present age of Dave is 40 years
Step-by-step explanation:
Let the present age of Johns be x
We are given that Dave is six years less then twice Johns age.
Dave's present age = 2x-6
We are also given that The sum of John and Dave's ages is 63.
So, [tex]x+2x-6=63[/tex]
[tex]3x-6=63[/tex]
[tex]3x=63+6[/tex]
[tex]3x=69[/tex]
[tex]x=\frac{69}{3}[/tex]
[tex]x=23[/tex]
Dave's present age = 2x-6=2(23)-6=40
Hence The present age of Dave is 40 years
