Study Notes
One-Step Algebra Equations
- One-step algebra equations have a single operation involving a variable and a constant.
- One-step algebra equations are easier to solve because they require only one operation to isolate the variable.
Solving Word Problems
- The key to solving word problems is to identify the unknown quantity and represent it with a variable.
- Students often find word problems challenging because they involve translating words into mathematical symbols and then applying the appropriate operations.
Translating Words to Math
- The phrase 'four less than a number' translates to x - 4, where x represents the unknown number.
- 'Less than' translates to the subtraction symbol (-).
Solving for the Unknown
- The first step in solving a word problem is to translate the words into a mathematical equation.
- In the equation x - 4 = 8, the variable x is on the left side of the equation because the word problem states 'four less than a number', implying subtraction from the unknown number.
Isolate the Variable
- To isolate the variable (x) in the equation x - 4 = 8, you need to perform the opposite operation of subtraction, which is addition.
- Add 4 to both sides of the equation to isolate the variable x on one side.
Solution
- The solution to the equation x - 4 = 8 is x = 12.
