If we assume the age of Francos is x, then dad will be 3x
In 10 years
Francos = x+10
Dad    = 3x+10
Therefore, 3x+10 =2(x+10)+2
                  3x +10 = 2x+20+2
                           x = 22-10
                            x =12 
Therefore, the present ages will be
Francos = 12 years
 Dad      = 36 years

Let

Y
 be the age of Franco's dad.
X  Franco's age

Y = 3*X                           (1)
(Y +10) = 2*(X+10) +2            (2
)


(3*X  +10) = 2*X +20 +2   

(3-2)X = 22 -10

X = 12 years old  (Franco)

Y = 3*12 = 36 years old (Franco's dad)

If we graph both lines we can get the solution of the system (point of intersection)

The best estimate is (x,y) = (-2.625, 0.688)</span>
