# Algebraic method to balance redox equations

diffrac
Hi all,

I'm learning how to solve redox equations. I found the algebraic method to solve equations such as this one:
Fe$^{2+}$ + Cr$_{2}$O$_{7}$$^{2-}$ +H$^{+}$$\rightarrow$ Fe$^{3+}$ + Cr$^{3+}$ + H$_{2}$0
and i was able to solve it.

What I don't see is how to use that algebraic method to solve an equation without superscripts; since it doesn't allow you to balance the charges, right?
like for example: NaOH + Cr(OH)$_{3}$ + NaClO$\rightarrow$ Na$_{2}$CrO$_{4}$ +NaCl + H$_{2}$O

$$0\times a_1 + 0\times a_2 + ... = 0\times b_1 + 0\times b_2 + ...$$
