Hello,

I solve an matrix with:
Solve[%, {a, b}]

This works, i get the answers for a and b.
Then i like to use the variables a and b in an formula wich i want to plot. This doesn't work.

I don't now what is rong?

Please help!

Wim

file:

p = {{1, 2}, {3, 4}}
MatrixForm[p]
Det[p]

p.{a, b} == {5, 6}

Solve[%, {a, b}]

w = x (a^2 + 2*b)
Plot[w, {x, 0, 6000}]
Plot[x*(-4^2 + 2*9/2), {x, 0, 6000}]
