Question

-21(2x-21)+24(24-3x)-29=30(x+30)-22(-3-22)​

Answer 1

Ответ:

-21(2x-21)+24(24-3x)-29=30(x+30)-22(-3-22)​

-42х+441+576-72х-29=30х+900+66+484

-42х-72х-30х=900+66+484-441-576

144х=433

х≅3

Answer 2

Ответ:

Если х там, где я думаю (3х-22) последняя скобка, то ответ -1,89

Пошаговое объяснение:

-21*2х - 21*(-21) + 24*24 - 24*3х - 29 = 30*х + 30*30 - 22*(-3х) - 22*(-22);

-42х + 441 + 576 - 72х - 29 = 30х + 900 + 66х + 484;

-42х - 72х - 30х - 66х = 900 + 484 - 441 - 576 + 29;  

-210х = 396;

х = 396 : (-210);

х = -1,89.

Answer 3

To solve the given equation, let's follow the steps to simplify and solve for the value of "x":

-21(2x - 21) + 24(24 - 3x) - 29 = 30(x + 30) - 22(-3 - 22)

Let's simplify each term step by step:

1. Distribute the coefficients: -42x + 441 + 576 - 72x - 29 = 30x + 900 + 66

2. Combine like terms on both sides of the equation: -42x - 72x + 441 + 576 - 29 = 30x + 66 + 900 + 66

Simplify: -114x + 988 = 30x + 966

3. Move all terms containing "x" to one side and constants to the other side: -114x - 30x = 966 - 988

Simplify: -144x = -22

4. Divide by the coefficient of "x" (-144) on both sides of the equation: x = (-22) / (-144)

Simplify: x = 11 / 72

So, the solution to the equation is x = 11/72.
