It should be negative 1 over z.
(1/x) - (1/y) = (1/z) Get the left-hand side over a common denominator:- (y-x)/xy = 1/z Take the reciprocal of both sides:- z = xy / (y-x)
z/7 + 5 = 12 z/7 = 12 - 5 = 7 z = 7 x 7 = 49
1 divided by 25 multiplied by z to the third power
7+7z 7=7*1 7z=7*z 7(1+z) is factored form

(w/x) / (y/z)
7 (seven)
2.5
Z=153.
7+7z 7=7*1 7z=7*z 7(1+z) is factored form
x = yz/(y - z)
If you mean: (3z/7) +9 = -7 then the value of z works out as -37 and 1/3
