Answer:

-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.
