# Thread: two unknowns in an equation

1. ## two unknowns in an equation

I have an equation with 2 unknowns "a" and "b" - I need to find a value for "b"

a=(b-c-(b*e))*d

is this possible?

Yes if d = 0 or e= 1

I don't know others Tell the complete question

3. Yes if d = 0 or e= 1

In this case d = f/100

4. a=(b-c-(b*e))*d
This is a real life money to KwH energy calculation i can assign values to c,d,e but have to be able to calculate an unknown a and an unknown b. UNfortunately my math isnt good enough to work out an equation that has two unknowns
