Question 667436: I need to know the rules for solving -x+3y=6 and x+3y=18. We are trying to figure out the proper way to solve these equations. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! -x+3y=6
x+3y=18
-----
Add the 2 equations and solve for "y":
6y = 24
y = 4
-------
Solve for "x":
x + 3y = 18
x + 3*4 = 18
x = 6
