Na+ and C2H3O2- (acetate) don't react.
Only Ag+ and Cl- do so by precipitation:
Ag+ + Cl- --> (AgCl)s
We see the chemical reaction but we write the chemical equation.
CH3CHO+HCl
Word equation:sodium + oxygen => sodium oxideSymbol equation:4Na + O2 => 2Na2O
Na2CO3.10H2O --> Na2CO3 + 10H2O
This reaction is:CH3CH2CH2CH2NH2 + HCl -------------->[CH3CH2CH2CH2NH3]Cl
hnc7h4so3 + h2o --> nc7h4so3- + h3o
That IS the equation. You may want to write with the equal sign: 6p = 24
-- take two quantities that are equal to each other -- write them both on the same line, with an "equals" sign between them ( = ) You now have an equation.
1-37
-9p - 15 = 93
There are no "following" data!
4x+8y=-24
It's not an equation - there's no "is" or "equals." You can write it as a mathematical *expression*, however:140 "decreased by 20%"140 - (20/100)*140
5x-4y=8
You cannot because it is not true.

3n=36 Write the equation n=12 Divide each side of the equation by 3 to get the variable alone.
