Answer:
<h3>present age of son = 10 </h3><h3>present age of father = 40</h3>Step-by-step explanation:
Let, present age of son be 'x'
present age of father be 'y'
y = 4x→ equation ( i )
After five years,
Son's age = x + 5
father's age = y + 5
According to Question,
Put the value of y from equation ( i )
Distribute 3 through the parentheses
Move variable to L.H.S and change it's sign
Similarly, Move constant to R.H.S. and change its sign
Collect like terms
Calculate the difference
Now, put the value of X in equation ( i ) in order to find the present age of father
plug the value of X
Calculate the product
Therefore,
Present age of son = 10
present age of father = 40
Hope this helps..
