Question

При х=4Решите пожалуйста с обьяснением

Answer 1

=$x* 7^{2x-3} *7 ^{4-2x} =x* 7^{2x-3+4-2x} =x*7 ^{1} =7*x$

при х=4 получаем 7*4=28

Answer 2

Solving for x when x = 4

To solve for x when x = 4, we can use the provided equation and apply the necessary steps to find the value of x.

The equation provided is not explicitly mentioned in the search results. However, based on the context, it seems like the equation might be x * 7 = 42. Let's solve this equation to find the value of x.

First, we can start by dividing 42 by 7 to find the value of x.

Step 1: - Divide 42 by 7 to find the value of x. - 42 ÷ 7 = 6 - Therefore, x = 6 [[SOURCE #2]].

Now, let's verify the value of x using the given equation.

Step 2: - Substitute the value of x (6) back into the equation x * 7 = 42 to verify. - 6 * 7 = 42 - Therefore, the value of x is indeed 6.

It seems there might be a discrepancy in the provided information. The equation x * 7 = 42 does not align with the initial statement "x = 4". If there is another equation or context related to x = 4, please provide additional details for further assistance.

If there are any other equations or specific details related to x = 4 that need to be addressed, please feel free to provide more information for further assistance.
