Dr. Fraser wil instructs you on how to use the Addition and Subtraction Techniques to solve basic equations. Using the two principles, you will isolate the variable to yield the answer. To make sure you understand fully, there are four video examples at the end of the lesson with an on word problems.
equation means finding all values of the variable that make the
To solve an
equation, isolate the variable on one side of the equation and with
a coefficient of 1.
You can do this by
using the addition and subtraction properties of equality: If you
add or subtract the same quantity to both sides of an equation, the
resulting equation has the same solutions as the original equation.
