Answer:
Step-by-step explanation:
N = 3rt^4 - 5rz
now factor r out
N = r(3t^4-5z)
divide by r on both sides
N/r = (3t^4 - 5z)
subtract (3t^4)
N/r - 3t^4 = -5z
now divide by -5 to isolate the variable (z)
[tex]\frac{(n/r)-3t^4}{-5}[/tex] = z
Answer:
(N-3rt^4) / -5r = z
Step-by-step explanation:
N = 3rt^4 - 5rz
Subtract 3rt^4 from each side
N-3rt^4 = 3rt^4-3rt^4 - 5rz
N-3rt^4 = - 5rz
Divide each side by -5r
(N-3rt^4) / -5r = - 5rz/ -5r
(N-3rt^4) / -5r = z
