Virtual Nerd: Solve for a Variable in a Fraction Using Multiplication First

Put all that algebra learning to use! Using algebraic strategies, learners solve three-variable systems. They then use the three-variable systems to write a quadratic equation given three points on the parabola.

Where did all these variables come from, anyway? The previous lessons in the series ask learners to solve multi-step equations using the distributive property, combining like terms, and using inverse operations. Now scholars solve...

Things get a little more complicated in this video, which features Sal solving several inequality problems involving multiplying and dividing by positive and negative numbers. Additionally, he shows a few more kinds of notation to...

Fractions!?! Learn how to solve an equation that has a fraction in it. The teacher shows how to multiply to eliminate fractions in an equation. She then shows the steps in solving the equation by further isolating the variable.

A multi-step equation with a fraction. Oh my! Just get rid of that fraction first and the rest will fall in to place. Follow the instructor as she takes you through the many steps to solving this equation.

Two variables in an equation and you want to solve for one in terms of the other. Watch the instructor demonstrate the steps to isolate each variable. She will use the subtraction rule of equality and the division rule of equality to...

One variable and two given values. Easy as pie, right? No, not for everyone. Word problems are often skipped over. This one is good for practicing. Identify the variable and figure out where the two given values go. Now solve.

Use the least common denominator to solve rational equations with variables in the denominators of algebraic fractions. Learners can watch this video to find out how to do just this! An instructor solves 2 problems by finding the least...

Choose from three video tutorials that relate to the Common Core standard HSA-CED.A.4. Topics covered include solving a formula for a variable, literal equations, and solving for a variable in terms of another variable.

There are many different ways to solve a system of linear equations. In this tutorial, you'll see how to solve such a system by combining the equations together in a way so that one of the variables is eliminated. Then, see how to find...
