Question

1) -6x-23+5x-x-7=16723-91+91*x=? если х=277. Решить.​

Answer 1

1) x=-23                  2) 723-91+25207=25839          

-2x-30=16

-2x=16+30

x=-23

-23*277= -6371

Answer 2

To solve the equation, we can substitute the value of x and then perform the calculations step by step. Let's solve it:

Given equation: -6x - 23 + 5x - x - 7 = 16723 - 91 + 91*x

Step 1: Substitute the value of x with 277:

-6(277) - 23 + 5(277) - 277 - 7 = 16723 - 91 + 91 * 277

Step 2: Perform the calculations:

-1662 - 23 + 1385 - 277 - 7 = 16723 - 91 + 25187

Step 3: Continue the calculations:

-196 * 11 = 16632

16723 - 91 + 25187 = 41819

So the equation becomes:

-196 * 11 = 41819

This equation is not valid since it leads to a contradiction. It seems that there might have been an error in the original problem or the value of x provided (x = 277) is incorrect.

Please double-check the equation or the value of x and provide the correct information if you would like further assistance.
