You use variables to stand for numbers in algebra
a variable is a letter that stand for another number
Sometimes... some variables can only stand for one thing, like m= slope, but "x" is a variable that can stand for just about anything; slope, axis, and equations.
X and Y do not stand for anything. They are merely letters that represent a variable in an algebraic equation. X is generally used as the first variable, and Y is used as the second variable, to differentiate the difference between two variables so one letter does not need to be used for two variables. In GRAPHS, they stand for the axis line. X is the horizontal axis, and Y is the vertical axis.
Since the Pythagorean Theorem deals with the relationship among the lengths of the sides of a right triangle, it is altogether fitting and proper, and a fortuitous coincidence, that the variables in the algebraic statement of the Theorem stand for the lengths of the sides of a right triangle.
The unknowns or variables
The variables stand for an unknown number that has not yet been identified which has been kept as a variable for the purpose of finding the value of.

Coefficients don't 'stand' for anything. They are numbers which multiply variables. For instance, in the expression 3 x + 2, three is the coefficient of x.
"G" in this context could stand for gravity, "p" could stand for pressure, and "s" could stand for speed. These are common scientific variables represented by these letters in equations and formulas.

"Solve an equation" means "find out, for which values of the variable or variables is the equation true".
No, in the context of environmental science, the letter "e" does not typically stand for "earth." It might represent other concepts or variables depending on the specific context.
It is one of two variables, conventionally plotted on the vertical axis in the coordinate plane.
