Question

2⋅(7x−8)−7⋅(2x+8)=−72

Answer 1

Ответ:

Уравнение является тождеством  - его решением является любое x

Answer 2

Ответ: любое число

Пошаговое объяснение:

2*(7x-8)-7*(2x+8)=-72

14x-16-14x-56=-72

14x-14x=-72+16+56

0x=0

Ответ: x- любое число

Answer 3

To solve the equation 2⋅(7x−8)−7⋅(2x+8)=−72, follow these steps:

1. Distribute the constants inside the parentheses: 14x - 16 - 14x - 56 = -72

2. Combine like terms on both sides of the equation: -16 - 56 = -72

3. Simplify the left side: -72 = -72

Since both sides of the equation are equal, this means that the original equation is true for all values of x. In other words, the solution is all real numbers (x can be any real number). This type of equation is called an "identity" equation because it's true for all possible values of x.
