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

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

What can you conclude about the work?
- The work was completed correctly.
- Both terms on the right side need to be divided by 3, not just the 36.

Answer :

Let's analyze the problem and walk through the steps to solve the given equation for [tex]\( y \)[/tex].

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

2. Goal: Solve for [tex]\( y \)[/tex].

3. Divide both sides by 3 to isolate [tex]\( y \)[/tex]:
[tex]\[
\frac{3y}{3} = \frac{36}{3} - \frac{5x}{3}
\][/tex]

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

5. Write the equivalent equation:
[tex]\[
y = 12 - \frac{5}{3}x
\][/tex]

Conclusion: The work was completed correctly. When dividing the right side, both terms ([tex]\(36\)[/tex] and [tex]\(5x\)[/tex]) should be divided by [tex]\(3\)[/tex]. This results in the simplified equation of [tex]\( y = 12 - \frac{5}{3}x \)[/tex]. There's no need for multiplication; only division was necessary to isolate [tex]\( y \)[/tex].
