Solve the Linear Equation: Finding y in 6+y=0

To solve this linear equation, we need to isolate the variable $y$. Here’s how:

We start with the equation:

$6 + y = 0$

To isolate $y$, we subtract 6 from both sides of the equation. This is because we want $y$ by itself on one side of the equation:

$6 + y - 6 = 0 - 6$

On the left side, the $+6$ and $-6$ cancel each other out, leaving us with:

$y = -6$

Therefore, the solution to the equation $6 + y = 0$ is $y = -6$.

Checking our solution against the provided choices, we see that the correct answer is choice 1: $y = -6$.
