Розвяжіть рівняння x :4 2/7 =3/5

Answer 1

Х:4 2/7=3/5
x=3/5*4 2/7         3/5*30/7=18/7=2 4/7
x=2 4/7
проверка  2 4/7:4 2/7=3/5
                  18/7:30/7=3/5
                   18/7*7/30=3/5
                    6/10=3/5
                    3/5=3/5

Answer 2

I can help you solve this equation. Here are the steps:

1. Multiply both sides of the equation by the least common multiple of the denominators, which is 28. This will clear the fractions and make the equation easier to solve.

$$28 \cdot \left( x + \frac{4}{2} + \frac{2}{7} \right) = 28 \cdot \frac{3}{5}$$

2. Simplify and distribute the 28 on both sides.

$$28x + 56 + 8 = 168$$

3. Combine like terms and subtract 64 from both sides.

$$28x = 104$$

4. Divide both sides by 28 to isolate x.

$$x = \frac{104}{28}$$

5. Simplify the fraction by dividing the numerator and denominator by 4.

$$x = \frac{26}{7}$$

This is the final answer. You can check it by plugging it back into the original equation and verifying that both sides are equal. You can also use an online calculator to solve equations like this one . I hope this helps. Have a nice day.
