The letters in an equation are called variables. They represent unknown values or quantities that can change. In addition to variables, equations may also include constants, which are fixed values. Together, they help express relationships between different quantities in mathematical expressions.
variables
The answer to the equation y x - x a would be x(y-1). When letters are used in a math expression, this is a form of math called Pre-Algebra or Algebra.
Let the number of postcards be ( p ) and the number of letters be ( l ). The cost equation can be set up as ( 0.15p + 0.25l = 2.65 ). Assuming you buy a combination of letters and postcards, you can solve this equation for different values of ( p ) and ( l ). One possible solution could be 5 postcards and 6 letters, as this combination satisfies the total cost.
Variable Equation. Equations typically always have (a) variable(s) so it's kind of like asking, "What a word that has letters called?" It's not quite the same, the question is valid. I'm just pointing out that it's a little redundant to say the following, but the best match for what you need would probably be: variable equation.
Without an equality sign the given letters can't be considered to be an equation.

An equation that has several letters or variables is a polynomial
In a mathematial equation the letters wither represent a variable or a constant.
The number and variables when next to each other in an equation are called a term. The variable or letters are coefficients.4x + 3x = 28.4x and 3x are terms and the variable "x" is the coefficient.
In an equation b or any other letters usually denotes the unknown variable.
