Analyze the work used to write an equivalent equation for [tex] y [/tex].

Given:
[tex] 3y = 36 - 5x [/tex]

1. Divide both sides by 3:
\[
\begin{aligned}
\frac{3y}{3} & = \frac{36}{3} - \frac{5x}{3} \\
y & = 12 - \frac{5x}{3}
\end{aligned}
\]

What can you conclude about the work?

A. The work was completed correctly.

B. Both sides needed to be multiplied by 3, rather than divided by 3.

C. When dividing 36 by 3, the answer should have been [tex] \frac{1}{12} [/tex], not 12.

D. Both terms on the right side need to be divided by 3, not just the 36.

Answer :

Let's go through the steps to determine if the equation for [tex]\( y \)[/tex] was solved correctly.

We start with the original equation:

[tex]\[ 3y = 36 - 5x \][/tex]

To solve for [tex]\( y \)[/tex], we need to isolate it on one side of the equation. We do this by dividing every term in the equation by 3. Let's break it down:

1. Divide both sides of the equation by 3:

[tex]\[
\frac{3y}{3} = \frac{36}{3} - \frac{5x}{3}
\][/tex]

2. Simplify each part:

- The left side becomes:
[tex]\[
y
\][/tex]

- The term [tex]\(\frac{36}{3}\)[/tex] on the right side simplifies to:
[tex]\[
12
\][/tex]

- The term [tex]\(\frac{5x}{3}\)[/tex] remains:
[tex]\[
\frac{5}{3}x
\][/tex]

3. Write the final equation:

[tex]\[
y = 12 - \frac{5}{3}x
\][/tex]

The division was applied correctly to every term of the equation, giving us the equivalent equation [tex]\( y = 12 - \frac{5}{3}x \)[/tex].

Therefore, we can conclude: The work was completed correctly.
