Question #73bfa

Answer 1

`x=5; y=2`

Explanation:

We are given two linear equations:

`2x+y=17` `(i)`

`x-y=-2` `(ii)`

We ADD `(i)` and `(ii)`, i.e.

`2x+cancely+x-cancely=15`

`3x=15`, thus `x=5`, and substituting this back into `(i)` or `(ii)`, and `y=7`. Does this fit? Do not trust my arithmetic!
