Answer 2

Let's solve each equation step by step:

1. 3x + 6 = 2(2x - 7) - x

Expand the right side of the equation: 3x + 6 = 4x - 14 - x

Combine like terms: 3x + 6 = 3x - 14

Subtract 3x from both sides to isolate the variable: 6 = -14

The equation is inconsistent, which means there is no solution. The original equation leads to a contradiction.

2. 6 * 2(3 - 2x) = 20 - (12 * 4x + 1 * 4)

Simplify the expression inside the parentheses on both sides: 6 * 2 * (3 - 2x) = 20 - (12 * 4x + 4)

Multiply within the parentheses: 12 * (3 - 2x) = 20 - (12 * 4x + 4)

Distribute 12 to the terms inside the parentheses: 36 - 24x = 20 - (48x + 4)

Remove the outer parentheses on the right side: 36 - 24x = 20 - 48x - 4

Combine like terms on the right side: 36 - 24x = 16 - 48x

Move all the terms involving x to one side of the equation: -24x + 48x = 16 - 36

Combine like terms: 24x = -20

Divide both sides by 24 to solve for x: x = -20/24

Simplify the fraction: x = -5/6

Therefore, the solution to the equation is x = -5/6.
