Find Elimination 7y+2x=11,3x-y=5

Solution:
Your problem `->` Elimination 7y+2x=11,3x-y=5


`7y+2x=11`

`:.2x+7y=11`

and ` 3x-y=5`

`:.3x-y=5`

`2x+7y=11 ->(1)`

`3x-y=5 ->(2)`

equation`(1) xx 1 =>2x+7y=11`

equation`(2) xx 7 =>21x-7y=35`

Adding `=>23x=46`

`=>x=46/23`

`=>x=2`

Putting `x=2` in equation `(1)`, we have

`2(2)+7y=11`

`=>7y=11-4`

`=>7y=7`

`=>y=1`

`:. x=2" and "y=1`
