Question

Solve the simultaneous equation x + y = 2 and x - y = 1​

Answer 1

(3/2, 1/2)

Explanation:

Solve by elimination:

`x+y=2\\+x-y=1`

The y's cancel

`2x=3`

Divide by 2

`x=(3)/(2)`

Plug back in

`(3)/(2) +y=2`

subtract

`y=2-(3)/(2)`

`y=(1)/(2)`

So, your answer:

`((3)/(2),(1)/(2))`
