Algebraic expression
It does not have an equal sign; its algebraic because it has a variable 2y-5
An algebraic expression is a mathematical phrase that contains variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. The variables in an algebraic expression represent unknown values or quantities, while the constants represent fixed values that do not change. The variables are typically represented by letters such as x, y, or z.
For example, the algebraic expression 3x + 4y – 2z represents a combination of three variables, x, y, and z, that are being added and subtracted with different coefficients. The coefficient refers to the number that is multiplied by the variable. In this case, x has a coefficient of 3, y has a coefficient of 4, and z has a coefficient of -2.
Algebraic expressions are commonly used in solving equations and formulating mathematical models in different fields such as science, engineering, and finance.
