WebbSimplification of an algebraic expression can be defined as the process of writing an expression in the most efficient and compact form without affecting the value of the original expression. The process entails collecting like terms, which implies adding or subtracting terms in an expression. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an ‘equal’ sign. The most basic and simple algebraic equations … Visa mer Some of the math equations used in algebra are: 1. Linear Equation A linear equation may have more than one variable. A linear equation is an equation in which the highest … Visa mer A math expression is different from a math equation. An equation will always use an equal (=) operator between two math expressions.
