Step 1: What are we trying to find? A number. Step 2: Assign a [|variable] for the number. Let’s call it //n //. Step 3: Write down what the [|variable] represents. Let //n // = a number Step 4: Write an equation.
 * Linear Equations, Word problem: **
 * When 6 is added to four times a number, the result is 50. Find the number. **

We are told 6 is added to 4 times a number. Since n represents the number, four times the number would be 4 //n //. If 6 is added to that, we get. We know that answer is 50, so now we have an [|equation]

Step 5: Solve the equation.

Step 6: Answer the question in the problem The problem asks us to find a number. We decided that //<span style="color: #454545; font-family: 'Arial Unicode MS','sans-serif'; font-size: 19px;">n //<span style="color: #454545; font-family: 'Arial Unicode MS','sans-serif'; font-size: 19px;"> would be the number, so we have //<span style="color: #454545; font-family: 'Arial Unicode MS','sans-serif'; font-size: 19px;">n //<span style="color: #454545; font-family: 'Arial Unicode MS','sans-serif'; font-size: 19px;"> = 11. The number we are looking for is 11. <span style="color: #454545; font-family: 'Arial Unicode MS','sans-serif'; font-size: 19px;">Step 7: Check the answer. <span style="color: #454545; font-family: 'Arial Unicode MS','sans-serif'; font-size: 19px;">The answer makes sense and checks in our [|equation] from Step 4.
