Solve N = 3rt^4 - 5rz
(solve for z)

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)

= z

(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
