Question

3.1/5+2.2/5-x=3.1/10-1.1/5

Answer 1

Ответ:

3,7.

Пошаговое объяснение:

3 1/5 + 2 2/5 - x = 3 1/10 - 1 1/5

3,2 + 2,4 - x = 3,1 - 1,2

5,6 - х = 1,9

х = 5,6 - 1,9

х = 3,7

Ответ: 3,7.

Проверка:

3 1/5 + 2 2/5 - 3 7/10 = 3 1/10 - 1 1/5

3 2/10 + 2 4/10 - 3 7/10 = 3 1/10 - 1 2/10

1 9/10 = 1 9/10 - верно.

Answer 2

Ответ:

Пошаговое объяснение:

3. 1/5 + 2. 2/5 - х = 3. 1/10 - 1. 1/5

5. 3/5 - х = 3. 1/10 - 1. 1/5

5. 6/10 - х = 3. 1/10 - 1. 2/10

5. 6/10 - х = 2. 11/10 - 1. 2/10

5. 6/10 - х = 1. 9/10

х = 5. 6/10 - 1. 9/10

х = 4. 16/10 - 1. 9/10

х = 3. 7/10

Answer 3

To solve the equation $\frac{3.1}{5} + \frac{2.2}{5} - x = \frac{3.1}{10} - \frac{1.1}{5}$, you can follow these steps:

1. Add the fractions on both sides of the equation: $\frac{3.1}{5} + \frac{2.2}{5} = \frac{3.1}{10} - \frac{1.1}{5}$

   $\frac{3.1 + 2.2}{5} = \frac{3.1}{10} - \frac{1.1}{5}$

   $\frac{5.3}{5} = \frac{3.1}{10} - \frac{1.1}{5}$

2. Simplify the fractions: $1.06 = 0.31 - 0.22 - x$

3. Subtract the numbers on the right side of the equation: $1.06 = 0.09 - x$

4. Now, isolate $x$ by moving the 0.09 to the other side of the equation: $x = 0.09 - 1.06$

5. Subtract 0.09 from 1.06 to find the value of x): \( x = -0.97

So, the solution to the equation is $x = -0.97$.
