Solving dependent equations

I am new to MathCAD and do not know how to approach this problem.

From the following equations, how do I determine P1 and P2 in MathCAD?

F=P1+P2

d1=(P1*L1)/(A1*E)

d2=(P2*L2)/(A2*E)

d1=d2

Valery,
That's nice, I would not have thought of that.

But, for a new user, a solve block might be easier to start with.

Valery has shown how this can be calculated symbolically.

Can you provide a worksheet, as this might be able to be solved numerically.

Attached is a worksheet that has all the information in it but is not solvable. Hope this is what you were asking for.

Thanks,
