Question

What does it mean for an equation to be balanced and why must you keep an equation in balance?

Answer 1

Mathematics or Stoichiometry?

Balanced: What goes in is what comes out.
Unbalanced: Matter and anti-matter mix and the universe is destroyed!

Answer 2

when two expressions are equal to one another , they can be equated to one another in an equation,
\[4=3+1\]
and equation is a bit like a set of scales,

if you add the same amount of something to both sides do a balanced set of scales they will stay balanced,

\[4+10=3+1+10\]
also if you subtract the same amount from balanced scales they will remain balanced
\[4+10-2=3+1+10-2\]

this also works with multiplication
\[\frac{4+10-2}4=\frac{3+1+10-2}4\]
