Question

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

Answer 1

Answer:

The value of x is 3 and y is 6.

Step-by-step explanation:

You can solve this simultaneous equation by elimination method :

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

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

$(1) + (2)$

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

$- x = - 3$

$x = 3$

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

$(2)⇒$

$3 - y = - 3$

$- y = - 6$

$y = 6$
