Answer 1

-8x-2.

Explanation:

1. Write the expression.

`2(x - 1) + 5(x - 3x)`

2. Solve parentheses using the associative property of multiplication.

`[(2)(x)+(2)(-1)]+[(5)(x)+(5)(-3x)]=\\ \\(2x)+(-2)+(5x)+(-15x)=\\ \\2x-2+5x-15x`

3. Simplify.

`-15x+2x+5x-2=\\ \\-8x-2`

4. Express your result.

-8x-2.
