4n - 132 = 88 + 132 +132 4n = 220 / / 4 4 n = 55
30.76 if n=4 and 4 nis substituted into the equation the equation the becomes 4x7.69 which equals 30.76

Let the numbers be 'm' & 'n' Hence mn = -40 And m + n = 6 It follows m = 6 - n Substitute (6 - n) n = -40 6n - n^2 = -40 n^2 - 6n - 40 = 0 Factor (n - 10)(n + 4) = 0 n = 10 & n = -4 => m = 6 - - 4 = 10
n + 1/4 = 9/20 n + 5/20 = 9/20 n = 4/20 = 1/5
This gives us the equations: n = xy = yx x != y (Note that for this example, the != stands for not equal to similar to some programming languages.) xy always equals yx due to the communtative property of multiplication. So there are actually an infinite number of answers. Some are given below: 6 = (2)(3) = (3)(2), 2 != 3 12 = (3)(4) = (4)(3), 3 != 4

125+n if n=67 is eqaul to 125+67=132
4n-16 = 88 add 16 to both sides of equation 4n = 104 divide both sides by 4 n = 26
-4
n=1 is the the lowest level there is.
if n=4 then n+1 would be 4+1 which equals 5
N= 5.5
30.76 if n=4 and 4 nis substituted into the equation the equation the becomes 4x7.69 which equals 30.76
When n = 4, 3n = 3*4 = 12
(n + 4)(n - 4)
n/4 = 8 n = 8*4 n = 32
