Уравненич.25 x+13x-18=276.846÷(7x-23)=18.29x-11x+18=414.968÷(9x-23)=44

Answer 1

Х + 13х - 18 = 276                   846 : (7х - 23) = 18
14х = 276 + 18                        7х - 23 = 846 : 18
14х = 294                                7х - 23 = 47
х = 294 : 14                             7х = 47 + 23
х = 21                                      7х = 70
                                                 х = 70 : 7
                                                 х = 10

29х - 11х + 18 = 414                968 : (9х - 23) = 44
18х = 414 - 18                          9х - 23 = 968 : 44
18х = 396                                 9х - 23 = 22
х = 396 : 18                              9х = 22 + 23
х = 22                                       9х = 45
                                                 х = 45 : 9
                                                 х = 5

Answer 2

To solve the given equations, let's go step by step. It appears that there are multiple equations, so we'll solve each one individually.

1. 25x + 13x - 18 = 276.846 / (7x - 23)

Step 1: Combine like terms on the left side. 38x - 18 = 276.846 / (7x - 23)

Step 2: To eliminate the fraction on the right side, we'll cross-multiply. 38x - 18 = 276.846 * (7x - 23)

Step 3: Distribute on the right side. 38x - 18 = 1937.922x - 6385.358

Step 4: Move all terms involving x to the left side and constants to the right side. 38x - 1937.922x = -6385.358 + 18 -1899.922x = -6367.358

Step 5: Solve for x. x = -6367.358 / -1899.922 x ≈ 3.3507

2. 18.29x - 11x + 18 = 414.968 / (9x - 23)

Step 1: Combine like terms on the left side. 7.29x + 18 = 414.968 / (9x - 23)

Step 2: To eliminate the fraction on the right side, we'll cross-multiply. 7.29x + 18 = 414.968 * (9x - 23)

Step 3: Distribute on the right side. 7.29x + 18 = 3734.712x - 9565.064

Step 4: Move all terms involving x to the left side and constants to the right side. 7.29x - 3734.712x = -9565.064 - 18 -3727.422x = -9583.064

Step 5: Solve for x. x = -9583.064 / -3727.422 x ≈ 2.5702

Please note that these solutions are approximations, and I have kept the answers in decimal form. If you need the solutions in fraction or rounded form, let me know. Also, the solutions may need to be verified as the provided equations seem quite unusual, and there may be a possibility of errors or inconsistencies in the original question.
