Question 238677
6x+2y-4=0 
10x+7y=-8
-----------
Rearrange
6x + 2y = 4
10x+ 7y = -8
--------------------
Multiply thru the 1st Eq. by 7
Multiply thru the 2nd Eq. by 2
--------------------
42x + 14y = 28
20x + 14y = -16
------------------------
Subtract the 2nd equation from the 1st:
22x = 44
x = 2
--------------------
Subtract x=2 into 6x+2y = 4 to solve for "y":
6*2 + 2y = 4
2y = -8
y = -4
