Question

В2. При каких значениях х значения выражений -4(3x-1)и 4(5х + 2) равны?Ответ:​

Answer 1

Ответ:

-0,5

Пошаговое объяснение:

$-4(3x-1) = 4(5x + 2)\\\\-12x+4 = 20x + 8\\\\-12x-20x = 8-4\\\\-8x = 4\\\\x = -0,5$

Answer 2

To find the values of x for which the expressions -4(3x-1) and 4(5x + 2) are equal, we need to set the two expressions equal to each other and then solve for x.

Equating the two expressions:

-4(3x - 1) = 4(5x + 2)

Now, let's solve for x:

Expand both sides:

-12x + 4 = 20x + 8

Move the variables to one side and the constants to the other side:

-12x - 20x = 8 - 4

Combine like terms:

-32x = 4

Now, divide both sides by -32:

x = 4 / -32

x = -1/8

So, the value of x for which the expressions -4(3x-1) and 4(5x + 2) are equal is x = -1/8.
