francos dad is three times his age. in 10 years, francos dad will be twice francos age plus 2. How old are franco and his dad no w?
2 answers:
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 ageY = 3*X (1) (Y +10) = 2*(X+10) +2 (2 ) (3*X +10) = 2*X +20 +2 (3-2)X = 22 -10X = 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>
