Probably not -- the question probably only asks them to find a particular voltage instead of all of them. Finding one is generally sufficient to demonstrate the necessary knowledge and skill without requiring a lot of additional time that really doesn't demonstrate much else.Wait. Does this mean you already found voltages across R2, R3, R4, R5, R6, R7?
Your Sarcasm-O-Meter is off. You should turn it on.Probably not -- the question probably only asks them to find a particular voltage instead of all of them.

You already have a couple of voltage sources labeled V1 and V2. It would be confusing to use the same symbols to label the nodes; I would use something like E1, E2, etc., to label the nodes.apologies i didn't read that @The Electrician, well so far i've labelled the nodes. V1 is where the branches with R6 and R7 connect. V2 is where the branch with R4 connects the middle branch. V3 is the node directly to the left of V2 and V4 is on the top branch between R2 and R5. I have the values for all the components, i just need to find the voltage across R1. I'm not sure if my nodes are correct ?
n2 and n3 are the same node. so first step is replace those two nodes with one.all the values are labelled now and the nodes are coloured in dark green and labelled with n's. it's homework and had to be done using the node method which i find very difficult. i've made some equations though. n1-n2/6 is the first. then n3-n4/8 is the second. From here i'm confused as what to do.
You need to properly track your units. You also need to learn about order of operations. The equation n1-n2/6 is the same as (n1) - (n2/6) which is NOT the same as (n1 - n2)/6. This should be written as (n1 - n2) / 6 Ω. Also, notice that this is NOT an equation. And equation involves an equals sign. All you have are a couple of disembodied expressions.all the values are labelled now and the nodes are coloured in dark green and labelled with n's. it's homework and had to be done using the node method which i find very difficult. i've made some equations though. n1-n2/6 is the first. then n3-n4/8 is the second.
