Question

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

Answer 1

`x=2` `y=1`

Explanation:

`2x-y=3`
`x+y=3`
cancel `+y` and `-y` then add `2x +x` and put it equal to `3+3`
then solve it and `x=2` after that put in equation 1 which is `2x -y=3` now place the value of x in this equation `2(2) -y=3` now solve the equation `4-y=3`
`-y=-1` cancel the minus sign and the ans will be `y=1`
