# FAQ: How To Solve Equations With Absolute Value?

## How do you solve an equation with absolute value?

SOLVING EQUATIONS CONTAINING ABSOLUTE VALUE (S)

1. Step 1: Isolate the absolute value expression.
2. Step2: Set the quantity inside the absolute value notation equal to + and – the quantity on the other side of the equation.
3. Step 3: Solve for the unknown in both equations.

## Can you solve problems using absolute value?

Solving absolute value equations is as easy as working with regular linear equations. The only additional key step that you need to remember is to separate the original absolute value equation into two parts: positive and negative (±) components.

## How do you solve a linear equation with absolute value?

You begin by making it into two separate equations and then solving them separately. An absolute value equation has no solution if the absolute value expression equals a negative number since an absolute value can never be negative. You can write an absolute value inequality as a compound inequality.

## What are the 3 major steps to solving an absolute value equation?

We will be using the following 3 – step process that can be used to solve any absolute value equation:

• STEP ONE: Isolate the Absolute Value.
• STEP TWO: Solve for Positive AND Solve for Negative.

## How do I simplify an expression?

To simplify any algebraic expression, the following are the basic rules and steps:

1. Remove any grouping symbol such as brackets and parentheses by multiplying factors.
2. Use the exponent rule to remove grouping if the terms are containing exponents.
3. Combine the like terms by addition or subtraction.
4. Combine the constants.

## Why do some absolute value equations have one solution?

In the case of only one solution, you end up with an absolute value expression equal to zero. Since this means that the distance from zero on the number line is zero, you end up with only one equation.

## What is common for the equations that have no solution?

Explanation: When finding how many solutions an equation has you need to look at the constants and coefficients. If the coefficients are the same on both sides then the sides will not equal, therefore no solutions will occur.

## Which equation has only one solution?

A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point.
