It looks like you've already done that. But you won't get useful help from us if we don't know the problem your trying to solve.viv12345 said:Need help setting up the equations to solve for the unknowns.
Are you asking how to solve this system of 3 equations and 3 unknowns?viv12345 said:I get the general idea but not sure how to begin actually solving the problem

Have you tried the method I described in post 2?viv12345 said:Yea, so I need to solve for i1, i2, and i3. I simplified the first equation to 1.56-118i1-75i3=0 from 1.56-43i1-75(i1+i3)=0 and did the same for the second equation but I don't know where to go from there. I'm just trying to follow what my professor did but after simplifying the equations, he picked a random number with no explanation to solve the equation so I'm really confused.
A simultaneous equation is a set of two or more equations that contain two or more unknown variables. The goal is to find the values of the variables that satisfy all of the equations at the same time.
Loop equations involve a closed path in a circuit, while junction equations involve the flow of current into and out of a junction point. Loop equations are used to solve for unknown voltages, while junction equations are used to solve for unknown currents.
To solve simultaneous equations using loop equations, you first label the unknown voltages in the circuit. Then, you write loop equations for each closed path in the circuit, using Kirchhoff's voltage law. Finally, you solve the resulting system of equations to find the values of the unknown voltages.
To solve simultaneous equations using junction equations, you first label the unknown currents in the circuit. Then, you write junction equations for each junction point in the circuit, using Kirchhoff's current law. Finally, you solve the resulting system of equations to find the values of the unknown currents.
Some tips for solving simultaneous equations include: identifying the type of equations (loop or junction), labeling the unknown variables, writing the equations accurately, using the correct laws (Kirchhoff's voltage law for loop equations and Kirchhoff's current law for junction equations), and solving the system of equations using methods such as substitution or elimination.
