Step-by-step explanation:
you multpy 25 by 8 to get your answer
Father = x
son = y
x-5 = 7(y-5)
x +5 = 3(y+5) solve the system
x-5 = 7y-35
x+5 = 3y +15
x-5 = 7y-35
-x-5 = -3y -15
-10 = 4y -50
+50 +50
40 = 4y
10 = y
Solve for X
x+5 = 3(10) + 15
x+5 = 45
x = 40
The father is 40yrs old and the son is 10yrs old.
