Solve for y

Question

-2x - y = 10

Answer 1

To solve for y, we need to isolate the variable y on one side of the equation.

Starting with the given equation:

-2x - y = 10

Let's move the -2x term to the right side of the equation by adding 2x to both sides:

-2x - y + 2x = 10 + 2x

Simplifying the left side gives:

-y = 2x + 10

Next, multiply both sides of the equation by -1 to isolate y:

-1 * -y = -1 * (2x + 10)

This results in:

y = -2x - 10

Therefore, the solution for y is y = -2x - 10.
