Question

В) 3(2х + 7) – 2 = 2(3х – 1)

Answer 1

Ответ:

0≠-21

Объяснение:

3(2x+7)-2=2(3x-1)

6x+21-2=6x-2

6x-6x=-2-21+2

0≠-21

Answer 2

To solve the equation 3(2x + 7) - 2 = 2(3x - 1), we'll start by simplifying both sides of the equation using the distributive property and combining like terms:

On the left side: 3(2x + 7) - 2 = 3 * 2x + 3 * 7 - 2 = 6x + 21 - 2 = 6x + 19

On the right side: 2(3x - 1) = 2 * 3x - 2 * 1 = 6x - 2

Now, the equation becomes: 6x + 19 = 6x - 2

We can see that the variable "x" appears on both sides of the equation. Let's isolate the variable by moving all the terms containing "x" to one side:

6x - 6x + 19 = 6x - 6x - 2

Simplifying further: 19 = -2

The equation 19 = -2 is not true. In fact, there is no value of "x" that satisfies this equation. Therefore, the original equation 3(2x + 7) - 2 = 2(3x - 1) has no solution.
