Answer:
The answer is
[tex]y = \frac{rw - 6f}{f} [/tex]
Step-by-step explanation:
[tex] \frac{rw}{6 + y} = f[/tex]
Cross multiply
We have
f(6 + y) = rw
6f + fy = rw
Move 6f to the right side of the equation to make fy stand alone
That's
fy = rw - 6f
Divide both sides by f to isolate y
That's
[tex] \frac{fy}{f} = \frac{rw - 6f}{f} [/tex]
We have the final answer as
[tex]y = \frac{rw - 6f}{f} [/tex]
