Question

8 18/21+(58/21-x)=11 3/21​

Answer 1

Ответ:

Пошаговое объяснение:

58/21 - х = 11. 3/21 - 8. 18/21

58/21 - х = 10. 24/21 - 8. 18/21

58/21 - х = 2. 6/21

х = 58/21 - 2. 6/21

х = 2. 16/21 - 2. 6/21

х = 10/21

Answer 2

To solve for the variable "x" in the equation:

8 18/21 + (58/21 - x) = 11 3/21

First, let's convert the mixed numbers into improper fractions for easier calculations.

8 18/21 can be written as (21 * 8 + 18)/21 = (168 + 18)/21 = 186/21

11 3/21 can be written as (21 * 11 + 3)/21 = (231 + 3)/21 = 234/21

Now, the equation becomes:

186/21 + (58/21 - x) = 234/21

Now, we can subtract 186/21 from both sides of the equation to isolate the term with "x":

(186/21 + 58/21) - x = 234/21

To combine the fractions on the left side:

(186 + 58)/21 - x = 234/21

244/21 - x = 234/21

Now, let's isolate "x" by moving 244/21 to the other side of the equation:

x = 244/21 - 234/21

x = (244 - 234)/21

x = 10/21

So, the solution for "x" is:

x = 10/21
