solve this equation for b?....
i/a+i/b=3/c
---
Subtract i/a from both sides
---
i/b = 3/c-(i/a)
---
Simplify the right side:
i/b = (3a-ic)/(ac)
---
Invert both sides:
b/i = (ac)/(3a-ic)
---
Multiply both sides by "i":
b = (aci)/(3a-ic)

Solve for b:
%28i%2Fa%29%2B%28i%2Fb%29+=+3%2Fc Add the fractions on the left side.
%28ai%2Bbi%29%2Fab+=+3%2Fc Cross-multiply.
aci%2Bbci+=+3ab Subtract bci from both sides.
aci+=+3ab-bci Factor b on the right side.
aci+=+b%283a-ci%29 Finally, divide both sides by (3a-ci).
highlight%28b+=+aci%2F%283a-ci%29%29
