Question

How do you solve `2x-y+2` and `2x+3y=22`?

Answer 1

Using addition and subtraction

Explanation:

Consider `2x-y+2` as equation (i) and `2x+3y=22` as equation (ii)

Subtracting (ii) from (i)
`2x+3y=22`
`-2x+y=2`

On solving we get `y=6`

Putting `y=6` in equation (ii) we get ,
`2x+18=22`

Giving `x=2`

`:.` `x=2` and `y=6`
