Answer:
n = m r - r t
Explanation:
Solve for n:
m = n/r + t
Hint: | Reverse the equality in m = n/r + t in order to isolate n to the left hand side.
m = n/r + t is equivalent to n/r + t = m:
n/r + t = m
Hint: | Isolate terms with n to the left hand side.
Subtract t from both sides:
n/r = -t + m
Hint: | Solve for n.
Multiply both sides by r:
Answer: n = m r - r t
