Question 1152812
y=-2x+6
3y-x+3=0
---------------
Since y is already given in terms of x, I'll use substitution.
======================
3y-x+3=0
3*(-2x+6) - x + 3 = 0
-6x+18 - x + 3 = 0
-7x = -21
x = 3
---------------
y=-2x+6
y = -6 + 6 = 0
---------------
---> (3,0)
===================================
If you want to solve for x & y, you should say that.
