<PRE><B>Question 1045369</B>
x + 2y = 0
x - y = 6


subtract the second equation from the first to get:


3y = -6


solve for y to get y = -2


replace y in either equation and solve for x to get:


x = 4


confirm by replacing x with 4 and y with -2 in both original equations to get:


x + 2y = 0 becomes 4 - 4 = 0 becomes 0 = 0
x + y = 6 becomes 4 + 2 = 6 becomes 6 = 6


the solutions are confirmed to be good.


this system of equations yields one solution.
