Answer 1

Answer:

Step-by-step explanation:

One friend has Xrs and another have Yrs

Acc to que

X+100=2(Y-100)

X-2Y=-300

This is 1 equation

6(X-10) =Y+10

6X-Y=70

This is 2 equation

By solving these 2 equations

By multiplying 2 with 2

12X-2Y=140

Doing 1-2

We will have

X-2Y-12X+2Y=-300-140

-11X=-440

X=40

Putting X=40 in 1

We will have

40-2Y=-300

2Y=340

Y=170

HENCE X=40 & Y=170
