Sure! Let's solve the equation [tex]\(-3x - y = -51\)[/tex] to find the value of [tex]\(y\)[/tex] when [tex]\(x\)[/tex] equals 15. Here are the steps:

1. Substitute [tex]\(x = 15\)[/tex] into the equation.
[tex]\[ -3(15) - y = -51 \][/tex]

2. Simplify the expression:
[tex]\[ -45 - y = -51 \][/tex]

3. To isolate [tex]\(y\)[/tex], add 45 to both sides of the equation:
[tex]\[ -45 - y + 45 = -51 + 45 \][/tex]

4. Simplify the right side:
[tex]\[ -y = -6 \][/tex]

5. Multiply both sides by -1 to solve for [tex]\(y\)[/tex]:
[tex]\[ y = 6 \][/tex]

So, the value of [tex]\(y\)[/tex] when [tex]\(x = 15\)[/tex] is [tex]\(y = 6\)[/tex].
