Solve the equation for the given variable.

Question

B=((r+z)/(2))m for r

Answer 1

To solve for r, we can isolate it by multiplying both sides of the equation by 2/B:

2/B * B = 2/B * ((r+z)/2)m

2 = (r+z)m

Then, divide both sides by m:

2/m = (r+z)

Finally, subtract z from both sides of the equation to solve for r:

r = (2/m) - z
