Translating Sentences into Equations
In this article, we will focus on the process of translating sentences into equations. This skill is essential in solving algebraic problems, as it allows us to represent real-life situations mathematically. By converting sentences into equations, we can then solve for the unknown variables and find the solutions. Let's explore several examples to understand this concept better.
1. Five More than 3 Times a Number is 26
Let's start with the sentence, "Five more than 3 times a number is 26." To convert this sentence into an equation, we begin by identifying the unknown variable, which we will represent as 'x.'
The equation would be: 3x + 5 = 26.
To solve this equation, we can subtract 5 from both sides: 3x = 21.
Next, we divide both sides by 3 to isolate 'x': x = 7.
Therefore, the value of the number in this case is 7.
2. Six Less than Five Times the Number is Nine
Now, let's consider the sentence, "Six less than five times the number is nine." Again, we need to identify the unknown variable, which we represent as 'x.'
The equation would be: 5x - 6 = 9.
To solve this equation, we can add 6 to both sides: 5x = 15.
Next, we divide both sides by 5 to isolate 'x': x = 3.
Hence, the value of the number in this case is 3.
3. The Difference between Four Times a Number and Seven is Five
Next, we have the sentence, "The difference between four times a number and seven is five." Let's assign the variable 'x' to represent the unknown number.
The equation would be: 4x - 7 = 5.
To solve this equation, we can add 7 to both sides: 4x = 12.
Afterward, we divide both sides by 4 to isolate 'x': x = 3.
Thus, the value of the number is 3.
4. Seven More than the Quotient of a Number and Three is Ten
Moving on, we encounter the sentence, "Seven more than the quotient of a number and three is ten." Let's use 'x' to represent the unknown number.
The equation would be: x/3 + 7 = 10.
To solve this equation, we can subtract 7 from both sides: x/3 = 3.
Next, we multiply both sides by 3 to isolate 'x': x = 9.
Therefore, the value of the number in this case is 9.
5. Five Less than Three Times the Sum of a Number and Four is 22
Lastly, we will analyze the sentence, "Five less than three times the sum of a number and four is 22." Let 'x' denote the unknown number.
The equation would be: 3(x + 4) - 5 = 22.
To solve this equation, we simplify the left side: 3x + 12 - 5 = 22.
Then, we combine like terms: 3x + 7 = 22.
Next, we subtract 7 from both sides: 3x = 15.
Finally, we divide both sides by 3 to isolate 'x': x = 5.
Hence, the value of the number is 5.
These examples illustrate how to translate sentences into equations and solve for the unknown values. By following these steps, You can effectively solve algebraic problems and find solutions.
