You can put this solution on YOUR website! 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)

You can put this solution on YOUR website! Solve for b: Add the fractions on the left side. Cross-multiply. Subtract bci from both sides. Factor b on the right side. Finally, divide both sides by (3a-ci).
