***************************************
Equation is a mathematical statement, in symbols, that two things are exactly the same (or equivalent). Equations are written with an equal sign. Yes, you can solve for a variable in an equation.
Example: 2+3+5=10
Expression is a symbol or combination of symbols that represents a quantity or a relationship between quantities. No, you cannot solve for a variable in an expression. Still, you can simplify it.
