It could represent an unknown variable in an expression or an equation.
It could be x/16 or 16/x. The x could be substituted by any other letter, for example, y/16 or 16/y.
It could be: 6.3-2 = 4.3
An equation has the 'equals' sign ( = ) in it. An expression hasn't.
n-5 is an expression, it cannot be a solution. Furthermore, there are infinitely many possible equations for which n = 5 could be a solution - even with the added requirements of the question.
an algebraic expression has no = sign. it could be like x+4, but an equation has to have an = sign. like x+4=5

It could be an expression or an equation or inequality.
It could be: 6.3-2 = 4.3
It could be an equation or an expression or a condition.

It could be anything since y squared plus y is an expression, not an equation.
"3x + 2y - x + 2y" is an expression that is often part of an equation; possibly a linear equation, though it could be of higher order as there could be squares, cubes etc. To be definite there would be an equals sign (=) and an expression, usually a number, the other side of it.
there is no answer.... what does this expression equal? you could simplify to -17.5d-8 but still without an equals sign there is no solutionTiesonthewall: Well, you can still reduce the equation without having it equal something.So in this case the fully reduced equation would be:* -17.5d - 8 It would just be an algebraic expression. Not necessarily an equation.
A math expression is basically and equation without and equals sign. For example "15a+30b" would be an expression, while "15a+30b=45c" would be an equation. An expression can also be defined as a sum of terms.it could also be defined as a mathematical phrase which involves or contain variables and numbers.like(x and y)these are variables.
