Question

(3 1/7-n)+1 4/7=35/7+2/7​

Answer 1

$(3\frac{1}{7}-n)+1\frac{4}{7}=3\frac{5}{7}+\frac{2}{7}\\\\(\frac{22}{7}-n)+\frac{11}{7}=\frac{26}{7}+\frac{2}{7}\\\\\frac{33}{7}-n=\frac{28}{7}\\\\n=\frac{33}{7}-\frac{28}{7}\\\\n=\frac{5}{7}$

Answer 2

Дано:

$(3 \frac{1}{7} - n) + 1 \frac{4}{7} = \frac{35}{7} + \frac{2}{7}$

Задание: Найти N (Решить уравнение)

Решение:

$(3 \frac{1}{7} - n) + 1 \frac{4}{7} = \frac{35}{7} + \frac{2}{7} \\ 3 \frac{1}{7} - n = 5 \frac{2}{7} - 1 \frac{4}{7} \\ 3 \frac{1}{7} - n = 3 \frac{5}{7} \\ - n = \frac{4}{7} \\ n = - \frac{4}{7}$

Ответ:

-4/7

Проверка:

$(3 \frac{1}{7} + \frac{4}{7} ) + 1 \frac{4}{7} = \frac{35}{7} + \frac{2}{7} \\ 3 \frac{5}{7} + 1 \frac{4}{7} = 5 \frac{2}{7} \\ 5 \frac{2}{7} = 5 \frac{2}{7}$

Answer 3

Let's solve the equation step-by-step:

(3 1/7 - n) + 1 4/7 = 35/7 + 2/7

First, we need to convert the mixed numbers to improper fractions:

3 1/7 = (3 * 7 + 1) / 7 = 22 / 7 1 4/7 = (1 * 7 + 4) / 7 = 11 / 7

The equation now becomes:

(22/7 - n) + 11/7 = 35/7 + 2/7

Next, combine like terms on both sides:

(22/7 - n + 11/7) = (35/7 + 2/7)

Now, let's add the fractions inside the parentheses on both sides:

(22/7 - n + 11/7) = 37/7

To eliminate the fractions, we'll find a common denominator, which is 7 in this case.

(22 - 7n + 11) = 37

Now, combine the constants:

33 - 7n = 37

Next, isolate the term with "n" on one side of the equation. We want to get "n" by itself, so we'll move the constant to the other side by subtracting 33 from both sides:

-7n = 37 - 33

-7n = 4

Finally, divide both sides by -7 to solve for "n":

n = 4 / -7

n = -4/7

So, the solution to the equation is:

n = -4/7
