Linear equations may be solved by isolating the variable or variables. Solving linear equations involves undoing whatever operations have been done to the variable and putting the variable alone on one side of the equal ... More » Math Algebra

To write linear equations from word problems, the student must first decide which quantities to assign variables to, and then decide what operations must be performed in order to solve the problem. For example, the unkno... More » Math Numbers

The drag equation is a formula used to calculate the force of drag experienced by an object due to movement through a fully enclosing fluid. The drag equation is D = Cd * A * .5 * r * V^2. The drag equation states that d... More » Science Physics Motion & Mechanics

Linear graphs represent the behavior of dependent variables that sit along a straight line with regard to independent variables, while nonlinear graphs represent variables that don't. Common functions that result in nonl... More » Math Algebra

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 » Math Algebra

Multistep equations with variables on both sides include 4x + 3 = 8x + 6, 2y + 7 = 4y - 2, 2x + 3y = 4(x - 1) + 2y and 3z(x + 4) = 2z + 3xy. Each equation is solved by moving terms from one side of the equal sign to the ... More » Math Algebra
