Introduction

In mathematics, solving equations is a fundamental concept that helps us understand the relationship between variables and constants. When we are given an equation, we need to determine if a particular value satisfies the equation. In this case, we are asked to find out if $s = 112$ is a solution to the equation $9 = \frac{s}{28}$ . To answer this question, we need to substitute the value of $s$ into the equation and check if it holds true.

Understanding the Equation

The given equation is $9 = \frac{s}{28}$ . This is a simple algebraic equation where we have a fraction on the right-hand side. To solve for $s$ , we need to isolate the variable $s$ on one side of the equation. We can do this by multiplying both sides of the equation by the denominator, which is $28$ .

Solving for $s$

To solve for $s$ , we multiply both sides of the equation by $28$ :

9 \times 28 = \frac{s}{28} \times 28

This simplifies to:

252 = s

Checking if $s = 112$ is a Solution

Now that we have solved for $s$ , we need to check if $s = 112$ is a solution to the equation. We can do this by substituting $s = 112$ into the original equation:

9 = \frac{112}{28}

To simplify this, we can divide $112$ by $28$ :

\frac{112}{28} = 4

Conclusion

As we can see, $4$ is not equal to $9$ , which means that $s = 112$ is not a solution to the equation $9 = \frac{s}{28}$ . Therefore, the correct answer is:

B. No

Why is $s = 112$ not a Solution?

$s = 112$ is not a solution to the equation $9 = \frac{s}{28}$ because it does not satisfy the equation. When we substitute $s = 112$ into the equation, we get $4$ , which is not equal to $9$ . This means that $s = 112$ does not satisfy the equation, and therefore, it is not a solution.

What is the Correct Solution?

To find the correct solution, we need to solve for $s$ using the equation $9 = \frac{s}{28}$ . We can do this by multiplying both sides of the equation by $28$ :

9 \times 28 = \frac{s}{28} \times 28

This simplifies to:

252 = s

Therefore, the correct solution is $s = 252$ .

In this article, we will answer some frequently asked questions related to solving equations and provide additional tips and resources.

Q&A

Q: What is the correct solution to the equation $9 = \frac{s}{28}$ ?

A: The correct solution to the equation $9 = \frac{s}{28}$ is $s = 252$ .

Q: How do I solve for $s$ in the equation $9 = \frac{s}{28}$ ?

A: To solve for $s$ , you can multiply both sides of the equation by $28$ :

9 \times 28 = \frac{s}{28} \times 28

This simplifies to:

252 = s

Q: What if I have a more complex equation, such as $2x + 5 = 11$ ? How do I solve for $x$ ?

A: To solve for $x$ in the equation $2x + 5 = 11$ , you can first subtract $5$ from both sides of the equation:

2x + 5 - 5 = 11 - 5

This simplifies to:

2x = 6

Next, you can divide both sides of the equation by $2$ :

\frac{2x}{2} = \frac{6}{2}

This simplifies to:

x = 3
