Answer 2

Answer:

Let Dad = Y, Son = X

Mathematically, from your statement:

Y = 3X, and (Y+10) + (X+10) = 68

Solving for X in 2nd equation, X = 48-Y

Insert this into first equation and solve for Y:

Y = 3(48-Y)

Y= 144 - 3Y

4Y = 144

Y = 36

Now, solve for X using either equation. I rearranged the 1st equation for X:

X = Y/3

X = 36/3 = 12

The boy is 12 and the dad is 36
