Question

7х – (х + 3) = 3(2х + 1)

Answer 1

Ответ:7х - (х + 3) = 3 * (2х - 1);

7х - х - 3 = 6х - 3;

7х - х - 6х = -3 + 3;

0 = 0.

Answer 2

Let's solve the equation step by step:

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

First, let's simplify the equation by removing the parentheses:

7x - x - 3 = 6x + 3

Next, combine like terms on both sides of the equation:

6x - 3 = 6x + 3

To isolate the variable, let's move all terms containing x to one side and the constant terms to the other side:

6x - 6x = 3 + 3

The x terms on the left side cancel each other out:

0 = 6

However, this leads to an inconsistent equation where 0 is equal to 6, which is not possible. Therefore, there is no solution to this equation.
