Answer:

Eliminating method

Step-by-step explanation:

For the given situation i.e.

3x + y = 1

And,

4x + y = 2

Here we use the elimination to determine the value of x and y

So,

3x + y = 1

4x + y = 2

- - -

-x = -1

x = 1

Now put the value of x in any of the above equation

So,

3 + y = 1

y = -2
