Question 178606

How do i solve 
3x-6y=30 
y=-6x+34 
-----------
Modify to get:
x - 2y = 10
y = -6x + 34
-----------
Substitute to solve for "y":

y = -6(2y+10) + 34

y = -12y - 60 + 34
13y = -26
y = -2
-------------
Substitute to solve for "x":
x -2*-2 = 10
x = 6
============================
Ans: x = 6 and y = =2
