Question

five years later, I shall be two and a half times as old as by son. write a linear equation in two variables to represent this statement.

Answer 1

Answer:

Let my age and son's age be x and y years.

Given, x = 3y

x + 5 = 5(y + 5)/2

=> 3y + 5 = 5(y + 5)/2 = (5y + 25)/2

=> 6y + 10 = 5y + 25

=> y = 15

x = 3 X 15 = 45

Hence, my age and son's age are 45 years and 15 years.

Answer 2

Answer:

so here is your answer

pls mark it as brainliest

Step-by-step explanation:

now let the present age of mine be x years and that of my son be y years

so according to given condition

x+5=2×1/2×(y+5)

=(2×2)+1/2(y+5)

=4+1/2(y+5)

=5/2(y+5)

ie 2(x+5)=5(y+5)

ie 2x+10=5y+25

so 2x-5y=15

hope it helped you a lot
