Question

the marks scored by ramesh is 8 more than twice of marks suresh.write this statement in linear equation in two variables.

Answer 1

Here is the answer

Let the marks scored by Ramesh be 'x'.

Let the marks scored by Suresh be 'y'.

According to the condition,

Marks of Ramesh = 8 + 2 [ Marks of Suresh ]

$\therefore x = 8 + 2y$
$x - 8 - 2y = 0$

Hence ,
The required linear equation is
x - 8 - 2y = 0 or x = 8 + 2y.

Answer 2

It can be done by two methods:-

Method 1:--

Let Suresh's marks be X and Ramesh's marks be y.

ATQ:-

Ramesh's marks=8+2(Suresh's marks)
y=2x+8

Method 2:-

Let the total marks scored be y and he marks scored by Suresh be X.

ATQ:-:-

Ramesh's marks+Suresh's marks=total
2x+8+x=y

I would suggest you to do it by method 1.
