Please show us what you have tried and exactly where you are stuck.Hi,
I'm having trouble understanding the below re-arrangement.
Please note: B = 4 and Y1 = 2.25
I'm rusty on general rules. Can any help?
Thanks!

I'm having trouble understanding the below re-arrangement.
It's wrong. [MATH]\; \text{v}_1[/MATH] has disappeared.
Thank you, but sorry I forgot to mention V1 = 2

To start simplify:
\(\displaystyle \frac{10}{4*y_2} \ = \ \frac{V_1 * b * y_1}{b * y_2} \ + \ \frac{V_w * b * y_1}{b * y_2} - V_w \)
\(\displaystyle \frac{2.25}{y_2} \ = \ \frac{V_1 * y_1}{ y_2} \ + \ \frac{V_w * y_1}{ y_2} - V_w \)
move "terms" and isolate Vw and continue....
Good catch ...... That should have been 2.5 as in:Thank you Subhotosh!
I understand the right hand side (expanding out), but how did the 2.25 on the left come about? sorry if this is simple, just been a long time for me. Really appreciate your help
