Question

B) 7x - (x + 3) = 3(2x - 1);​

Answer 1

Ответ:

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

7x-x-3=6x-3

7x-x-6x=3-3

x=0

Answer 2

To solve the equation 7x - (x + 3) = 3(2x - 1), you need to simplify and isolate the variable x. Here are the steps to do that:

1. Start by simplifying both sides of the equation:

   7x - x - 3 = 6x - 3

2. Now, combine like terms on both sides of the equation:

   6x - 3 = 6x - 3

3. At this point, you can see that the equation is an identity, meaning that it's true for all values of x. This implies that there are infinitely many solutions for x, and any value of x will satisfy the equation.

So, in this case, there are no specific solutions for x; any real number for x will make the equation true.
