Algebra Help in Excel

[markdidham]

Hey,

Very rusty on Algebra, but I'm trying to solve an equation, and need help re-ordering it to solve for X.

Ib = I1*(D1/Dt)+X*(D2/DT)

If it helps work with these values:

Ib = 8.75
I1 = 5
I2 = X (Should be 10 when solved)
D1 = 10
D2 = 30
Dt = 40

The reorder would be Ib(Dt/D2)-I1(d1/d2) which gives us 10

Welcome to the Board!

I believe the equation should look like:

X = DT*(Ib-(I1*D1/dt))/D2
