Equations

Each form of a linear equation has its purpose — pupils just have to find it. Building on the previous lesson in the series, learners examine point-slope and standard form. Using point-slope form, pupils write the equation of a...

Use the distributive property to solve equations. The sixth lesson in a 33-part series has scholars solve equations that need to be transformed into simpler equations first. Class members apply the distributive property to the equations...

Here is an equation in which the first step is to use the distributive property to get rid of the parenthesis. Then it is solved for the variables. Since there are variables on both sides of the equation, it is important to verify the...

Sal is plotting away in this video - but don't worry, it's nothing suspicious. He introduces linear equations, taking viewers through a few simple examples before applying the knowledge to word problems that are more complicated.

Clarify the steps needed to solve a multi-step equation involving fractions. Sal solves for x in the equation x - 8 = x/3 +1/6, by demonstrating how he multiplies to clear out all of the fractions, isolates the variables, and then solves...

Sal adds a few more steps to these problems as he solves algebraic equations with two steps - though he states that "there's more than one way to do it." Those who become confused by increasingly complicated algebra problems on a test...

Sal demonstrates how to solve an equation. He begins by saying that the variable needs to be isolated. He shows how to move numbers on either side of the equal sign to isolate the variable. He also shows how to verify answers by plugging...

Sal offers an example showing how to manipulate numbers on either side of the equal sign to isolate the variable and solve the equation.

Here is an equation in which the first step is to use the distributive property to get rid of the parenthesis. Then it is solved for the variables. Since there are variables on both sides of the equation, it is important to verify the...

Zoe is decorating a cake for her grandpa's birthday and needs to know how many more candles to add. Follow along as she explains how to set up and solve algebraic equations in this step-by-step presentation. Equations with negative...
