Question

What is the solution of the system `3x - y = 3` and `2x + y = 2`?

Answer 1

Given
`3x - y = 3` and
`2x + y = 2`

By adding the two equations together, we get
`5x + 0 = 5`
So
`x=1`

Substituting `x=1` back into the first equation:
`3(1) - y = 3`
which implies
`y= 0`

The solution to the given equations is
`(x,y) = (1,0)`
