SO2 + 2NaOH --> Na2SO3 +H2O
For Na, left side Na=1, right side Na = 2
For S, left side S=1, right side S =1 (balance)
For O, left side O = 3, right side O = 4
For H, left side H = 1, Right side H = 2
So, we need to multiply NaOH by 2 to balance
Na, O, H at both side

to balance an equation you want every number of element same on both parts of the equation.
SO2+2NaOH--> Na2SO3+H2O
2H, 2Na, 4O, 1S--> 2H, 2Na, 4O, 1S
so the equation is now balanced

The answer is
4Na+3So2+2H+O ---> 2Na2So3+H2O
