Question

Х минус 3/21 равно 11/21 помогите пожалуйста

Answer 1

$\displaystyle x-\frac{3}{21}=\frac{11}{21}\\\\ x-\frac{1}{7}=\frac{11}{21}\\\\ x=\frac{11}{21}+\frac{1}{7}\\\\ x=\frac{2}{3}$

Answer 2

$x - \frac{3}{21} = \frac{11}{21} \\ x = \frac{11}{21} + \frac{3}{21} \\ x = \frac{14}{21} = \frac{2}{3}$

Answer 3

Solution:

To solve the equation x - 3/21 = 11/21, we can isolate the variable x by adding 3/21 to both sides of the equation. This gives us:

x = 11/21 + 3/21

Now, we can add the fractions together:

x = 14/21

Simplifying the fraction, we get:

x = 2/3

So, the solution to the equation x - 3/21 = 11/21 is x = 2/3.

This information is based on mathematical principles and the addition of fractions.

I hope this helps! If you have any other questions, feel free to ask.
