1. Solve linear equations x+y=2 and 2x+3y=4 using Elimination Method

Solution:
`x+y=2`

and `2x+3y=4`

`x+y=2 ->(1)`

`2x+3y=4 ->(2)`

equation`(1) xx 2 =>2x+2y=4`

equation`(2) xx 1 =>2x+3y=4`

Substracting `=>-y=0`

`=>y=0`

Putting `y=0` in equation`(1)`, we have

`x+0=2`

`=>x=2`

`:.x=2" and "y=0`
