Answer 2

Ответ:   x= -24

Пошаговое объяснение:

1/5(5/9x+5)-1/7(7/6x+2 1/3)=2

1/9x + 1 - 1/7 (7/6x + 7/3 )=2

1/9x + 1 - 1/6x - 1/3= =2

1/9x + 2/3 - 1/6x=2

2x + 12 - 3x=36

-x + 12=36

-x= 36 - 12

-x=24

Answer 3

To solve the given equation, let's first simplify and then isolate the variable 'x.'

1. Simplify the equation step by step: 1/5(5/9x + 5) - 1/7(7/6x + 2 1/3) = 2

   Distribute the fractions: (1/5)(5/9)x + (1/5)5 - (1/7)(7/6)x - (1/7)(2 1/3) = 2

   Simplify the fractions: (1/9)x + 1 - (1/6)x - (8/21) = 2

2. Combine the x terms and the constant terms: To combine the x terms, we need to find a common denominator for (1/9) and (-1/6), which is 18.

   (2/18)x - (3/18)x + 1 - (8/21) = 2

   Now, combine like terms: (-1/18)x - (8/21) + 1 = 2

   (-1/18)x + (13/21) = 2

3. Isolate the variable 'x': To isolate 'x,' we'll first move (13/21) to the other side of the equation by subtracting it from both sides:

   (-1/18)x = 2 - (13/21)

   Now, find a common denominator for 2 and (13/21), which is 42:

   (-1/18)x = (42/21) - (13/21)

   (-1/18)x = 29/21

   Finally, multiply both sides by (-18) to solve for 'x':

   x = (29/21) * (-18)

   x = -29/7

So, the solution to the equation is: x = -29/7.
