Answer 3

1. 2(3x - 5) + 4x

To simplify this expression, we'll start by distributing the 2 to both terms inside the parentheses:

2 * 3x - 2 * 5 + 4x

Now we can simplify further:

6x - 10 + 4x

Combining like terms:

(6x + 4x) - 10

10x - 10

The simplified expression is 10x - 10.

2. 7x + (x - 3)

We can simplify this expression by removing the parentheses:

7x + x - 3

Combining like terms:

(7x + x) - 3

8x - 3

The simplified expression is 8x - 3.
