My professor gave us the three equations for a circuit and said to find I1, I2, and I3 However, I cannot figure out how to solve it.(adsbygoogle = window.adsbygoogle || []).push({});

The equations:

I1 + I2 = I3

5 - 10*I1 -10 - 5*I3 = 0

5 - 5*I2 - 5*I3 - 10 = 0

Every time I try to solve it I end up with two unknown variables. How would you solve them? I am having difficulty solving systems of equations. A step by step guide would be a great help.

Thanks.

Stephen
