Answer:

y = 3, x = -3/2

Step-by-step explanation:

y - 2x = 6 ........ equation 1

+ y + 2x = 0 ......... equation 2

_________

2y + 0 = 6

2y = 6

y = 6/2

y = 3

Sub for y in equation 1

y - 2x = 6

3 - 2x = 6

Collect like terms

-2x = 6 - 3

-2x = 3

x = 3/-2

x = -3/2

Therefore y = 3, x = -3/2
