M = 5 * * * * * 4m + m - 11 = 9 or 5m - 11 = 9 so that 5m = 20 and then m = 4, NOT 5.
The Pert equation: (O+4M+P)/6, is basically a weighted average used to estimate a value. O= Optimistic (best) value M= Most likely value; multiplied by 4 because it is more likely. P = pessimistic (worst) value An average is the sum of a group of numbers divided by the count in the group. If we look at the Per Equation as: (O+4M+P)/6 = (O+M+M+M+M+P)/6, you can see the six items that are being averaged.
4m+9+5m-12=42 9m=45 m=5

If: -4m -7 = 17 Then: m = -6
2n + 4m - 2n + m = 5m
4m + 327m = 331m
Well, 3m + m = 4m so 88 divided by 4= 22 there fore m =22 and 3m = 66
-4m + 3 = -8 -4m = -8 -3 -4m = -11 4m = 11 m = 2.75

It is 4m.
mn - 4m - 5n + 20 = (mn - 5n) - (4m - 20) = n(m - 5) - 4(m - 5) = (m -5)(n - 4)
4m - 8 = 6m =>4m - 6m = 8 => -2m = 8 => m = -(8/2) => m = -4
