I realized it's a simple one....I am a beginner.
I want to use a for loop in which contain a quadruple simultaneous equation like this
r1,r2,r3,r4,r5,r6,r7 are given
v1,v2,v3,v5 are unknown
for rt= -100:400
(-5-v1)/r1+(v3-v1)/r4+(v2-v1)/rt=0
(v1-v2)/rt+(v3-v2)/r5+(5-v2)/r6=0
(5-v3)/r2+(v1-v3)/r4+(v5-v3)/r3=0
(0-v3)/r7+(v2-v3)/r5=0
end
And I want to plot v5/rt continuously
Anyone willing to help? Thanks!

No, you have 4 equations in 5 unknowns, v1, v2, v3, v4, v5. You can solve the 4 equations for any 3 of (v1, v2, v3, v4) together with v5, but you will find that v5 is expressed in terms of the one of the four variables you did not solve for.
You would need one more equation in order to be able to solve the system
