Product Mix Problem
The manager in a manufacturing firm is considering devoting the excess capacity to one or
more of products: ...
43,67/4,3=
a.x + b.y = e
c.x + d.y = f
a.d - b.c = 2
e.d - f.b = 1
a.f - e.c = -1
Find\:the\:\:11\:\:term\:of\:binomial\:expansion\:\:\left(x+y\right)^{17}
\frac{2un}{1+un}-un
0,125 x 320
x+y+z=16
5/2x+y+10z=40
2x+1/2y+4z=21
Solve this simultaneous equation in 3 variables
