14x
A mathematical expression in its' most simplistic form, merely assigns a value to a variable. Don't confuse an expression with an equation. An equation requires a solution. An expression cannot be "solved". It only allows you to determine the value of a variable. This is the expression in words "x is equal to 3" (X is the variable which is equal to the constant number 3) This is the expression in numbers "x=3" The expression in words "y is equal to 6" (Y is the variable which is equal to the constant number 6) The expression in numbers is "y=6" I hope you understand now.
the coefficient of the expression is 1 the coeffficient of the variable is 5
It is an expression, in a variable x. Since it is not an equation, it cannot be solved.

The variable in 14x is x.
It is an expression with a variable, x.It is an expression with a variable, x.It is an expression with a variable, x.It is an expression with a variable, x.
Because "x" is a variable, it is the same as 9 times x.
It is an expression whose value will depend on the value of the variable x.
3x5 ÷ 7y4
Yes. A variable by itself, or anything that contains a variable, would be a variable expression (unless the variable cancels out, as in "x - x", which always has the same value).
'x' is a fixed but unknown amount. It is not a VARIABLE!!!!
x = 6n/42 x = n/7
Yes

the letter in 2x+6. The variable is the x.
No. "x" is the variable. Any calculation involving a variable would be an EXPRESSION.
