Answer :

To solve the given equation and verify the solution, follow these steps:

1. Starting Equation:
[tex]\[ \frac{y}{3} = -6 \][/tex]

2. Given:
[tex]\[ y = -18 \][/tex]

3. Substitute [tex]\( y \)[/tex] in the original equation:

Substitute [tex]\( y = -18 \)[/tex] into the left-hand side of the equation:
[tex]\[ \frac{-18}{3} \][/tex]

4. Simplify the Left-Hand Side:

Perform the division:
[tex]\[ \frac{-18}{3} = -6 \][/tex]

5. Check the Result:

The left-hand side simplifies to [tex]\(-6\)[/tex], which matches the right-hand side of the original equation:
[tex]\[ -6 = -6 \][/tex]

6. Conclusion:

Since substituting [tex]\( y = -18 \)[/tex] into the equation [tex]\(\frac{y}{3} = -6\)[/tex] results in a true statement, [tex]\( y = -18 \)[/tex] is a correct solution.

Therefore, the solution to the equation [tex]\(\frac{y}{3} = -6\)[/tex] is [tex]\( y = -18 \)[/tex].
