3* x1 + x2 + S1 =105

x1 + x2 + S2 =37

x1 + 3* x2 + S3 =48

So when S1 & S2 were 0's i figured it out x1=34, x2=3 & S3=5 Then when S1 & S3 were both 0's I figured that out which took forever at 33.375,4.875 & -1.2. But i was just guessing and checking. Can someone please help me understand the correct way to solve these?

Thanks in advance.
