The expression you provided is:

0.5x(2) + y - 2x

Let's simplify it step by step:

0.5x(2) simplifies to x because 0.5 times 2 is 1:

x + y - 2x

Now, combine like terms by adding x and -2x:

x - 2x + y

x - 2x simplifies to -x:

-x + y

So, the simplified expression is:

-y + x

Объяснение: 0.5x⋅2+y−2x0.5 ↓

x+y−2x↓
