Answer 1

Ответ:

$x \ = \frac{9}{2}$

Answer 2

To solve the equation 9 - (x - 5) + 4×(6 - x) = 3 + 3 • (x + 20) - 2x, you'll want to simplify and isolate the variable x. Here's how you can do it step by step:

1. Start by distributing the constants outside the parentheses:

9 - x + 5 + 4*(6 - x) = 3 + 3*(x + 20) - 2x

2. Continue to simplify by performing the multiplication inside the parentheses:

9 - x + 5 + 24 - 4x = 3 + 3x + 60 - 2x

3. Combine like terms on both sides of the equation:

(9 + 5 + 24) - (x + 4x) = (3 + 60) - (3x + 2x)

38 - 5x = 63 - 5x

4. Notice that you have -5x on both sides of the equation. To isolate x, you can add 5x to both sides:

38 - 5x + 5x = 63 - 5x + 5x

38 = 63

5. This equation is not true; it has no solution. This means that there is no value of x that will satisfy the original equation. The original equation is inconsistent and has no solution.
