Answer 2

I can help you with your math problem. The user's message translates to "Answer in detail. 3/7 x = 4/21 very necessary !!!! Thanks in advance" .

To solve the equation, we need to isolate x on one side of the equation. We can do this by multiplying both sides by 7/3, which is the reciprocal of 3/7. This will cancel out the 3/7 on the left side and leave x alone. On the right side, we need to simplify the fraction by multiplying the numerators and denominators. The result is:

$$\frac{3}{7}x=\frac{4}{21}$$ $$\times \frac{7}{3}$$ $$x=\frac{4}{21}\times \frac{7}{3}$$ $$x=\frac{4\times 7}{21\times 3}$$ $$x=\frac{28}{63}$$

We can reduce this fraction by dividing both the numerator and denominator by 7, which is the greatest common factor of 28 and 63. The final answer is:

$$x=\frac{28}{63}$$ $$\div 7$$ $$x=\frac{4}{9}$$
