Question

3/4 * (x + 2) = 2, 4

Answer 1

Пошаговое объяснение: раскрываем скобки 3/4х+6/4=2.4

Переносим известное в право

3/4х=2.4-6/4

3/4х=2.4-1.5

0.75х=0.5

х=2/3

Answer 2

Ответ:

Пошаговое объяснение:

3/4х + 6/4 = 2. 4/10

3/4х = 2. 4/10 - 6/4

3/4х = 2. 2/5 - 1. 2/4

3/4х = 2. 8/20 - 1. 10/20

3/4х = 48/20 - 30/20

3/4х = 18/20

х = 18/20 : 3/4

х = 18/20 * 4/3

х = 6/5 * 1/1

х = 6/5

х = 1. 1/5

Answer 3

To solve the equation $\frac{3}{4} \cdot (x + 2) = 2 \cdot 4$, you can follow these steps:

1. Start by simplifying both sides of the equation: $\frac{3}{4} \cdot (x + 2) = 8$

2. Next, you can eliminate the fraction by multiplying both sides of the equation by the reciprocal of $\frac{3}{4}$, which is $\frac{4}{3}$: $\frac{4}{3} \cdot \frac{3}{4} \cdot (x + 2) = 8 \cdot \frac{4}{3}$

3. Simplify both sides further: $x + 2 = \frac{32}{3}$

4. Now, isolate $x$ by subtracting 2 from both sides of the equation: $x = \frac{32}{3} - 2$

5. To subtract fractions, you need a common denominator, which is 3 in this case. So, convert 2 to a fraction with a denominator of 3: $x = \frac{32}{3} - \frac{6}{3}$

6. Subtract the fractions: $x = \frac{32 - 6}{3}$

7. Finally, simplify the fraction: $x = \frac{26}{3}$

So, the solution to the equation $\frac{3}{4} \cdot (x + 2) = 2 \cdot 4$ is $x = \frac{26}{3}$.
