In algebra, the method of substitution is used to simplify problems by reducing the number of variables or quantities. The specific details of the solution depend on the original problem. More » Math Algebra

The key to solving Hardy-Weinberg equilibrium problems is understanding the following equations: p + q = 1 (p + q)^2 = 1 p^2 + 2pq + q^2 = 1 More »

To solve an algebra problem, identify the variable for which you are solving, isolate the terms containing that variable, and then solve the equation by isolating the variable itself. Check your work by plugging your ans... More » Math Algebra

Elimination is a method for solving a system of two or more algebraic equations by transforming the system so that one of the variables cancels out. It is sometimes called the addition method because it involves adding e... More » Math Algebra

In a ninth-grade Algebra I course, students learn to solve problems using the foundational rules of mathematical computations, and they learn to solve algebraic expressions to find the values of variables. Some Algebra I... More »

Basic problems in Algebra I typically teach students to solve one-step equations to find variables with addition, subtraction, multiplication and division. From there, students learn to solve two-step equations. More »

Elimination in mathematics refers to the elimination method, also called the addition method, which is used to solve basic algebraic problems by comparing two equations in order to find what their variables equal. This m... More » Math Algebra
