Question

How do you solve and find the ordered pairs x + y = 6 and x - y = 4?

Answer 1

`x=5`
`y=1`

Explanation:

Adding up the two equations `x+y=6` and `x-y=4`
We get
`x+y+x-y=6+4`
or
`2x+0=10`
or
`2x=10`
or
`x=10/2`
or
`x=5`--------------------Ans `1`

By putting the value of `x=5` in the equation `x+y=6`
we get
`5+y=6`
or
`y=6-5`
or
`y=1`-------------------Ans `2`
