Write an augmented matrix for the system. Use row operations to put it in row ecjelon form. Find y then back substitute to find x.

2x+10y=-12
-3x+y=34
I have the matrix and what to multiply it by except the last one. I'm really lost. Please help and show work. 

2   10     -12     *1/2
-3   1      34
 
1    5     -6    *3
-3   1     34
 
1   5      -6    
0   16     16
