Solve for Y

-2x - y = 10

1 answer

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

We can do this by moving -2x to the other side of the equation.

Starting with: -2x - y = 10

Add 2x to both sides of the equation:

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

Simplifying:

0 - y = 2x + 10

-y = 2x + 10

To isolate y, we can multiply both sides of the equation by -1:

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

Simplifying:

y = -2x - 10

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