: A number that, when substituted for the variable, makes the equality true is called a root or a solution. This section is foundational, introducing the concept of
If you are working through the exercises, you might encounter equations like: 13x−30=7x13 x minus 30 equals 7 x To solve this, you would group the terms together: from both sides: to both sides: Checking the result: 13(5)−30=3513 open paren 5 close paren minus 30 equals 35 7(5)=357 open paren 5 close paren equals 35 Since both sides are equal, is the correct root.
