One Step Multiplication Equations

Main idea of one step multiplication equations

A one step multiplication equation is when a variable is being multiplied by a number We solve by using the inverse operation division That is why we use division to isolate the variable

Definition of equation

A math sentence with an equal sign that shows two sides are the same

Definition of coefficient

The number with the variable the number that the variable is multiplied by

Definition of inverse operation

An operation that undoes another operation For multiplication the inverse operation is division

Example 1 Solve 5x = 10

Think what number times 5 equals 10 5 times 2 = 10 so x = 2 Check 5 times 2 = 10 true

Remember this about one step multiplication equations

To solve divide both sides by the coefficient Always check your answer by substituting it back into the original equation
