# Solving equation2

## Solving equation

(OP)
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

### RE: Solving equation

Try chapter one of any undergraduate chemical engineering text.

### RE: Solving equation

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)

coming !

### RE: Solving equation

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?

### RE: Solving equation

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

### RE: Solving equation

(OP)
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.

### RE: Solving equation

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
]

### RE: Solving equation

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]
