Question

13x ×20 - 4x - 16 +x =54​

Answer 1

Ответ:

70/257.

Пошаговое объяснение:

13x•20 - 4x - 16 +x =54

260х - 4х - 16 + х = 54

257х = 16 + 54

257х = 70

х = 70/257

Ответ: 70/257.

Второй вариант решения после комментария автора:

13x + 20 - 4x - 16 +x = 54

13x - 4x + x = 54 + 16 - 20

10х = 50

х = 50:10

х = 5

Ответ: 5.

Answer 2

To solve the equation 13x × 20 - 4x - 16 + x = 54, we'll follow these steps:

1. Simplify the equation: Multiply 13x by 20: 260x Combine like terms: 260x - 4x + x - 16 = 54 Simplify further: 257x - 16 = 54

2. Move the constant term to the other side of the equation by adding 16 to both sides: 257x - 16 + 16 = 54 + 16 Simplify: 257x = 70

3. Isolate the variable x by dividing both sides of the equation by 257: 257x/257 = 70/257 Simplify: x = 70/257

So, the solution to the equation 13x × 20 - 4x - 16 + x = 54 is x = 70/257.
