In my example, the letter "x" serves to represent a variable.
2x + 3 = 11
(x = 4)
An expression.
Variable expression.
A mathematical phrase with at least one variable is an expression that includes numbers, operations, and one or more letters representing unknown values. For example, the expression ( 3x + 5 ) contains the variable ( x ) and represents a relationship where ( x ) can take on different values. Another example is ( 2y - 7 = 0 ), which includes the variable ( y ) and represents an equation.
An algebraic expression contains variable numbers and at least one operation. For example, the expression (3x + 5) includes the variable (x) and the operations of addition and multiplication. Such expressions can represent a wide range of mathematical relationships and can be simplified or solved for specific variable values.
A combination of numbers, a variable, and at least one operation can be represented mathematically as an expression. For example, in the expression ( 3x + 5 ), ( 3 ) and ( 5 ) are numbers, ( x ) is the variable, and the operation is addition. This expression illustrates how numbers and a variable can interact through mathematical operations.

Variable expression.
That looks like the description of an EXPRESSION. However, an expression need not have "at least one operation"; a single number, or variable, is a perfectly valid expression.
An algebraic expression is a type of expression that contains a variable or variables.
An algebraic expression can have a mixture of numbers and variables, but it does not contain an equals sign.
yes it should contain one variable or more.
it is a one-step equation
