Dr.Fraser will cover Techniques for Multi-Step Equations in this video lesson. You will first learn what they are and then the strategy for solving such equations. The lesson concludes with four comprehensive examples.
equation contains more than one operation.
To solve such an
equation, undo the operations in the reverse order in which they
were performed in the equation. The last operation performed in the
equation is the first one to be removed, using the addition,
subtraction, multiplication, and division properties of equality.
In most equations,
the last operation performed is an addition or subtraction.
Therefore, begin by using these properties of equality. Then use
the multiplication or division property of equality to isolate the
Understand how to
solve word problems involving consecutive numbers. Consecutive
unknown numbers are called x and x + 1. Consecutive unknown even or
odd numbers are called x and x + 2.
