Question

Решите уравнение: 1) 6x + 8x-7x=714; 2) 23x-19x+5x = 1827; 3) 11x-6x+17x=2042; 4)5x+3x-47 = 6401

Answer 1

1) х*(6+8-7)=714. Далее 7х=714 и х=714:7=102... 2) х*(23-19+5)=1827. Далее 9х=1827 и х=1827:9=203... 3) х*(11-6+17)=2042. Далее 22х=2042 и х=2042:22=92,8... 4) х*(5+3)=6401+47. Далее 8х=6448 и х=6448:8=806... Если какие-то действия непонятны,пиши, я помогу

Answer 2

Решение уравнений:

1) 6x + 8x - 7x = 714

To solve this equation, we can combine like terms first: 6x + 8x - 7x = (6 + 8 - 7)x 6x + 8x - 7x = 7x So, the equation becomes: 7x = 714

Now, we can solve for x by dividing both sides by 7: 7x / 7 = 714 / 7 x = 102

Therefore, the solution to the first equation is x = 102.

2) 23x - 19x + 5x = 1827

Similarly, we can combine the like terms: 23x - 19x + 5x = (23 - 19 + 5)x 23x - 19x + 5x = 9x So, the equation becomes: 9x = 1827

Now, we can solve for x by dividing both sides by 9: 9x / 9 = 1827 / 9 x = 203

Therefore, the solution to the second equation is x = 203.

3) 11x - 6x + 17x = 2042

Combining like terms: 11x - 6x + 17x = (11 - 6 + 17)x 11x - 6x + 17x = 22x So, the equation becomes: 22x = 2042

Solving for x: 22x / 22 = 2042 / 22 x = 93

The solution to the third equation is x = 93.

4) 5x + 3x - 47 = 6401

Combining like terms: 5x + 3x - 47 = (5 + 3)x - 47 5x + 3x - 47 = 8x - 47 So, the equation becomes: 8x - 47 = 6401

Adding 47 to both sides: 8x = 6451

Solving for x: x = 806.375

The solution to the fourth equation is x = 806.375.

These are the solutions to the given equations.
