You could also substitute any number less than You would probably think that at least means less than. Note, for multiplication and division, it is not guaranteed that if you multiply by the variable you are solving for that the two sides are going to be equal.

Once the inequality is written, you can solve the inequality using the skills you learned in our past lessons. You will see how this works in the examples. These equations can make use of any letter as a variable.

The graphs section contains commands for plotting equations and inequalities. Now that we have isolated the variable on the left side of the equation, we can go about solving the new equation using techniques of solving one and two step equations.

The number of weeks that Keith can withdraw money from his account is 12 weeks or less. Solve This problem is typical of what you can expect to see in a multi-step equation.

Are you ready to dive into the "real world" of inequalities? It does not matter which side we choose. How many miles can Katie travel without exceeding her budget? Keep in mind that the variable does not always have to be x.

Send What can QuickMath do? How many weeks can Keith withdraw money from his account? We will then need to multiply both sides by the reciprocal of which is To get help solving more complicated equations, click here link to one var multi step. So if you subtract a number from one side, you MUST subtract the same value from the other side.

Even after doing that, there is still a 3 multiplied by the variable, so division will be necessary to eliminate it. However, most times, we have to use several properties to get the job done. It also has commands for splitting fractions into partial fractions, combining several fractions into one and cancelling common factors within a fraction.

Write your answer in a complete sentence. Since is equal tomy answer is correct. The other goal is to have the number in front of the variable equal to one.

Note that multiplication and division are inverse operations of each other. No more than are key words that note that this problem must be written as an inequality. Here are a few key words that we associate with inequalities! Word Problem Solving Strategies Read through the entire problem.

Solve This problem does not have the variable by itself on one side.Solving Word Problems in Algebra is easy if you know the key steps! Try solving these inequality word problems.

A two-step equation is as straightforward as it sounds. You will need to perform two steps in order to solve the equation. One goal in solving an equation is to have only variables on one side of the equal sign and numbers on the other side of the equal sign.

The other goal is to have the number in front of the variable equal to one. The variable does not. Learn how to solve linear equations that contain a single variable. For example, solve 2(x+3)=(4x-1)/2+7.

We'll use algebra to solve this percent problem. This is where we start getting into the heart of what algebra is about - solving equations. In this tutorial we will be looking specifically at linear equations and their solutions.
