Answer 1

Answer:

no, it is not possible☆☆

Step-by-step explanation:

some error in sum

If sum of age of two friends is 20

Then let

• Present age of one be Xyrs
• and others be 20-Xyrs

4 YRS AGO

According to the problem

20- X-4 * X -4= 40

20X-X^2+4X-80-4X+16=40

20X -X^2 =40-16+80

20X-X^2=120-16=104

20X-X^2=104

X-X^2=104/20

X-X^2=5.2

I dont know how to solve 2 variables

and i don't think its possible with so less information

sorry
