Hey, need some help with the methodology involved in solving simultaneous equations with three unknowns.
I1 = I2 + I3
8I1= 3I3
3I1+5I2=3.4
cheers.
First rearrange your second two equations to get them with respect to
, therefore
For the second one, do the same:
, , so .
Now put these values of and in to your first equation, you now have an equation in terms of just .
Solve this and then put your value for back into the second and third equations to find all terms.
