The equation you've provided can be simplified. Let's break it down:
\[ y = 2x - x \]
Subtract \( x \) from \( 2x \):
\[ y = (2x - 1x) \] \[ y = 1x \] \[ y = x \]
So, the simplified equation is:
\[ y = x \]
This represents a straight line with a slope of 1 that passes through the origin (0, 0). If you have any further questions or need assistance with related topics, feel free to ask!
