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

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

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

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 :

To analyze the work used to write an equivalent equation for [tex]\( y \)[/tex] from the equation [tex]\( 3y = 36 - 5x \)[/tex], let's break down the steps:

1. Start with the original equation:
[tex]\[
3y = 36 - 5x
\][/tex]

2. Divide every term of the equation by 3. This step is necessary to isolate [tex]\( y \)[/tex]. When dividing both sides of the equation by 3, you get:
[tex]\[
\frac{3y}{3} = \frac{36}{3} - \frac{5x}{3}
\][/tex]

3. Simplify each term:
- On the left side, [tex]\( \frac{3y}{3} = y \)[/tex].
- On the right side, [tex]\( \frac{36}{3} = 12 \)[/tex] and [tex]\( \frac{5x}{3} = \frac{5x}{3} \)[/tex].

4. Rewrite the simplified equation:
[tex]\[
y = 12 - \frac{5x}{3}
\][/tex]

5. Conclusion about the work:
The steps performed were correct with respect to the method used: dividing all terms by 3. Thus, the equivalent equation is [tex]\( y = 12 - \frac{5x}{3} \)[/tex].

Therefore, the operation of dividing all terms on both sides by 3 is correctly applied, and the rewritten equation is valid. The work was completed correctly.
