Question

29.1) 20 (x – 4) - 17 (3 - 2 x) = 58 + 33x;​

Answer 1

Ответ:

X=9

Объяснение:

20(x–4)-17(3-2x)=58+33x

20x-80-17(3-2x)=58+33x

20x-80-51+34x=58+33x

20x-131+34x=58+33x

54x-131=58+33x

54x-131-33x=58

21x=58+131

21x=189

x=9

Answer 2

To solve the equation 20(x - 4) - 17(3 - 2x) = 58 + 33x, follow these steps:

1. Distribute the constants on the left side of the equation to the terms inside the parentheses: 20x - 80 - 51 + 34x = 58 + 33x

2. Combine like terms on both sides of the equation: (20x + 34x) - (80 + 51) = 58 + 33x

   54x - 131 = 58 + 33x

3. Move the 33x term from the right side of the equation to the left side by subtracting 33x from both sides: 54x - 33x - 131 = 58

   21x - 131 = 58

4. Add 131 to both sides of the equation to isolate the term with x: 21x - 131 + 131 = 58 + 131

   21x = 189

5. Finally, divide both sides by 21 to solve for x: 21x/21 = 189/21

   x = 9

So, the solution to the equation is x = 9.
