Solve Two Step Equation Word Problems Easily

What is a Two-Step Equation?

A two-step equation is a type of algebraic equation that requires two steps to solve. It is a linear equation that involves one variable, and the solution can be found by performing two operations, such as addition and multiplication, or subtraction and division. Two-step equations are commonly used to solve word problems, where the equation represents a real-world scenario.

How to Solve Two-Step Equation Word Problems

To solve a two-step equation word problem, follow these steps:

• Read the problem carefully and identify the variable and the two operations involved.
• Translate the word problem into an equation, using the variable and the operations identified.
• Solve the equation by performing the two operations in the correct order.
• Check your solution by plugging it back into the original equation.

📝 Note: It's essential to read the problem carefully and identify the variable and operations correctly to ensure a correct solution.

Example of a Two-Step Equation Word Problem

Here’s an example of a two-step equation word problem:

“Tom has been saving money for a new bike and has 120 in his savings account. He wants to buy a bike that costs 180. Tom’s parents have agreed to give him an allowance of $5 per week for doing chores. How many weeks will it take Tom to have enough money to buy the bike?”

Let’s solve this problem step by step:

• Let x be the number of weeks it takes Tom to have enough money to buy the bike.
• The equation can be written as 120 + 5x = 180.
• To solve the equation, we need to isolate the variable x.
• Subtract 120 from both sides of the equation: 5x = 60.
• Divide both sides of the equation by 5: x = 12.

Therefore, it will take Tom 12 weeks to have enough money to buy the bike.

Tips and Tricks for Solving Two-Step Equation Word Problems

Here are some tips and tricks to help you solve two-step equation word problems easily:

• Read the problem carefully and identify the variable and operations involved.
• Use a variable to represent the unknown value.
• Translate the word problem into an equation, using the variable and operations identified.
• Use inverse operations to isolate the variable.
• Check your solution by plugging it back into the original equation.

🤔 Note: Inverse operations are opposite operations that can be used to isolate a variable. For example, addition and subtraction are inverse operations, as are multiplication and division.

Common Mistakes to Avoid

Here are some common mistakes to avoid when solving two-step equation word problems:

• Misidentifying the variable and operations involved.
• Translating the word problem into an equation incorrectly.
• Performing the operations in the wrong order.
• Not checking the solution by plugging it back into the original equation.

🚨 Note: Avoiding these common mistakes will help you solve two-step equation word problems accurately and efficiently.
