Question

five years hence a men age will be three times his sons age assuming their present agesto be x years and y years respectively write a linear eqution in terms of the body

Answer 1

Answer:

hence refer to past so we have to add Let father age will be =x and son age will be =y

x+5=3 (y+5)

x+5=3y+15

x-3y=15-5

x-3y=10

Answer 2

Answer:

x+5= 3y +15

Step-by-step explanation:

present ages of father and son are X and y respectively. five years later father's age = X+5 and son's age = y+5 . Father's age will be 3 times son's age therefore X+5 =3( y+5) simplifying this give us X+5 = 3y +15
