      Select the second and third equations to eliminate the same z variable (multiply the second equation by (3 and add). You now have two equations in terms of x and y. Use any method to solve this system for x and y (elimination is shown here). Substitute x = 3 and y = 4 into the second original equation and solve for z. 2((3) + 3(4) – z = 4. z = 2

      Now, we have to write equations for the dependent sources. The current iX is the current through the 4.7[k ] resistor. We can write. This gives us three equations in three unknowns, and we can solve. This problem can be solved fairly easily by substituting the third equation into the second, and then by substituting the second equation into the ...
