Re: equations with unknowns for 86
You must use a matrix to solve this problem.
Create a matrix like the following: (2nd MATRX)
[x y z w q p c]
[]
[]
[]
[]
[]
For each of your six equations, take the coefficients
of each variable and place them in columns 1 - 6 in the
matrix. Column 7 is for the constant (non-variable) term in each
equation. Also, the variables must align. (vertically, the x's y's and
so on must be on top of each other) Enter a 0 as a place holder if
any of these terms don't exist in one of the equations.
Now, exit the matrix editor, and run the "rref" function on the matrix.
This will display a new matrix. The far right column contains the six
answers to your equation in the order you specified.
ex:
input: x y z
output: x
y
z
Have fun!
