Question

10*(7*a-6)-7*(10*a+6)=-102

Answer 1

Ответ:

Пошаговое объяснение:

10*(7a-6)-7*(10a+6)= -102

70a - 60 - 70a - 42 = -102

-102 = -102

a  є (-∞ ; ∞)

Answer 2

Ответ:

a ∈ (-∞ ; ∞)

Пошаговое объяснение:

$10(7a-6)-7(10a+6)=-102$

$70a - 60 - 70a - 42 = -102$

$-102 = -102$

a ∈ (-∞ ; ∞)

Answer 3

Let's solve the equation step-by-step:

Given equation: 10*(7a - 6) - 7(10*a + 6) = -102

Step 1: Distribute the terms inside the parentheses. 10 * 7 * a - 10 * 6 - 7 * 10 * a - 7 * 6 = -102

Step 2: Simplify the terms. 70a - 60 - 70a - 42 = -102

Step 3: Combine like terms. (70a - 70a) - (60 + 42) = -102

Step 4: Further simplify. 0 - 102 = -102

Step 5: Solve. -102 = -102

The equation is true for all values of 'a.' In other words, it is an identity, and it means that the original equation is true for any value of 'a' you substitute into it.
