actually, in a addition to the question i posted a few minutes ago, can someone please help me with a few actual specific questions? thanks so much i'm very confused and i've been working on these all day.
*Literal Equations*
~solve for x
ax + bx = 8ab
~solve for y
my  ny = m  n
~solve for a
s = n/2 (a + 1)
~solve for n
C = ne / r + nr
~solve for n
a = (n2)180 / n

math 
drwls,
Here's how to do three of them. Once you see algebraic steps, you should be able to do the rest.
#1 ax + bx = 8ab
x(a+b) = ab
x = ab/(a+b)
#3 s = n/2 (a + 1)
a+1 = 2n/s
a = (2n/s) 1
#5 a = (n2)180 / n
a n = 180 n  360
n(180 a) = 360
n = 360/(180a)= 2/[1(a/180)]
(Either answer is correct)
