Answer 2

1. (3x - 1) - (4 - 6x) + 7

First, simplify within the parentheses: (3x - 1) - (4 - 6x) + 7 = 3x - 1 - 4 + 6x + 7 (distribute the negative sign) = 9x + 2

So, the simplified expression is 9x + 2.

2. 5 × (2a - 4) + 8(6a - 9)

First, simplify within the parentheses: 5 × (2a - 4) + 8(6a - 9) = 10a - 20 + 48a - 72 (distribute the multiplication) = 58a - 92

So, the simplified expression is 58a - 92.
