Solving equation 2

[sjjustine]

How do I solve the eq below.
y=x*m where m and y are four different values( y is known).
x is a constant. m is what I am looking for, for all different values y

Try chapter one of any undergraduate chemical engineering text.

Use the soslve-block as:

Given
Y = m . x
X(m,y) := Find(x)

y = [1 2 3 4]T

i := 1..4

Solution[i := X(m, y[i)

Thanks for your interest in

Mathemagician,

Thanks for help all of us with this brilliant answer. I vote for you a star.

Hacksaw, could you provide reference of any undergraduate chemical engineering text with similar answer?

The Mathmagician just presented it. Most of them use mad cad or some variation of it.

It do not work! My equation looks like this:
RatioArea:= constant*(molesx/molesref)
RatioArea1:={0.298,0.505,0.532,0.58}, RatioArea2:={0.279,0.182,0.073,0.046}
constant:=0.915
molesref:=0.031
Find molesx
I want to program this so that everytime I add new RatioArea it just automatically takes it and give me a new molesx with overwriting the old one.

RatioArea:={0.298,0.505,0.532,0.58}
i:=0..columns(RatioArea)-1
constant:=0.915
molesref:=0.031
molesx:=RatioArea*molesref/constant
molesx=[0.01 0.017 0.018 0.02
]

Sorry no need for range variable.

RatioArea:=[0.298 0.505 0.532 0.58]
constant:=0.915
molesref:=0.031
molesx:=RatioArea*molesref/constant
molesx=[0.01 0.017 0.018 0.02]
