Question

-2x + y = 0
x - y = -3

Answer 1

The value of x is 3 and y is 6.

Explanation:

You can solve this simultaneous equation by elimination method :

`- 2x + y = 0 - - - (1)`

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

`(1) + (2)`

`- 2x + y + x + (- y) = 0 + ( - 3)`

`- x = - 3`

`x = 3`

`substitute \: x = 3 \: into \: (2)`

`(2)⇒`

`3 - y = - 3`

`- y = - 6`

`y = 6`
