term: a single number, or variables and numbers connected by multiplication.

This number is called the coefficient of the variable.

coefficient: Sometimes a variable is multiplied by a number.

variables: variables are symbols that stand for an unknown quantity they are often represented with letters, like x, y, or z.

Use Properties of Equality to Isolate Variables and Solve Algebraic Equationsįirst, let us define some important terminology:

Absolute value extends into the concept of modulus for complex numbers.Steps with an end in sight.

The absolute value function is an example of a continuous but non-differentiable function (specifically at zero).Absolute value can be used in applications connecting algebra to geometry.If the absolute value expression is equal to a negative number there is no solution.Then the absolve value equation can be split into a 'positive' equation and a 'negative equation.' Treat the absolute value as a variable, and isolate the absolute value first.

Once the absolute value is isolated, the absolute value can you be though of under it's distance definition to increase efficiency.Absolute value represents distance, so | x − a | = c.Knowledge of the properties of equality and some experience with absolute value would help when performing this exercise. Solve the absolute value equation: This problem provides an absolute value equation and asks the student to find all solutions and write them in the space provided.There is one type of problem in this exercise: This exercise practices solving absolute value and recognizing how these are different from but related to linear equations. The Absolute value equations exercise appears under the Algebra I Math Mission and Mathematics II Math Mission.
