(z-9)(z+3
It's rare to see an equation with two equals signs. I'm guessing something else went in between 3z and 9. 3z + 9 = 15, then z = 2 3z - 9 = 15, then z = 8 3z x 9 = 15, then z = 5/9 3z/9 = 15, then z = 45
If you mean z-9=3, then z=12. That means you can make any algebraic expression that makes sense. e.g. z+1=13.

9 digits in a zip code
z decreased by 9 is z-9
6 + z/9 = 9 Therefore, z/9 = 3 3 x 9 = 27 Therefore, z = 27
It is the same as: 9*z*z*z*z
xy + z = 9Subtract 'z' from each side:xy = 9 - zDivide each side by 'x':y = (9 - z) / x
its either (z2+ 9)(z - 2) , (z2+ 2)(z - 9) , or (z2- 9)(z - 2)
If Z = 3, then (9 + 7Z) = [ 9 + 7(3) ] = 9 + 21 = 30
(z-9)(z+3
Z+359=9
To find the value of z, set up the equation: 9z = 135 (then divide both sides of the equation by 9) z = 15

(z - 9)(z + 5)
