To solve for y in the equation 2x - y = 6, you can rearrange the equation to isolate y. Add y to both sides of the equation to get:
2x - y + y = 6 + y
Simplifying, you get:
2x = 6 + y
Now, subtract 6 from both sides of the equation:
2x - 6 = 6 + y - 6
Simplifying further:
2x - 6 = y
So, y = 2x - 6.
