NO. an expression is a symbol or combination of symbols that represents a quantity or a relationship between quantities.
x-5=30 can be an expression. - sign doesnt matter.
a variable is one which doesnt have a fixed quantitative value.
eg. y=3x+5, here x and y are variables.
ur 2nd definition is alright, but its not the exact.
doing homework? good luck.

Your definition for expression is incorrect. It can have an equal sign. Variable is usually has a specific name for its purpose & holds an appropriate value. Usually it is for integers or whole numbers.
