Answer 2

To simplify the expression 5*(10-x) + (7x-5) - (70+3x), follow these steps:

1. Distribute the 5 to both terms inside the first set of parentheses:

   5*(10-x) = 50 - 5x

2. Distribute the negative sign to both terms inside the second set of parentheses:

   -(70+3x) = -70 - (-3x) = -70 + 3x

Now, the expression becomes:

50 - 5x + (7x - 5) - (70 + 3x)

3. Combine like terms:

   -5x + 7x - 5 - 3x = (-5x + 7x - 3x) - 5

   -x - 5

So, the simplified expression is:

• x - 5
