Understanding the Problem

To solve the given equation, we need to isolate the variable x. The equation involves fractions, so we will start by simplifying and combining the terms.

Simplifying the Equation

The given equation is:

\frac{3}{2}=\frac{3}{2x}-\frac{6}{5x}

To simplify the equation, we can start by finding a common denominator for the fractions on the right-hand side. The least common multiple of 2x and 5x is 10x.

Multiplying Both Sides by 10x

Multiplying both sides of the equation by 10x will eliminate the fractions:

10x \cdot \frac{3}{2} = 10x \cdot \left(\frac{3}{2x}-\frac{6}{5x}\right)

This simplifies to:

15x = 10x \cdot \frac{3}{2x} - 10x \cdot \frac{6}{5x}

Combining Like Terms

Now, we can combine the like terms on the right-hand side:

15x = 15 - 12x

Isolating the Variable x

To isolate the variable x, we can add 12x to both sides of the equation:

15x + 12x = 15

This simplifies to:

27x = 15

Solving for x

Finally, we can solve for x by dividing both sides of the equation by 27:

x = \frac{15}{27}

Simplifying the Fraction

The fraction $\frac{15}{27}$ can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 3:

x = \frac{5}{9}

Conclusion

Therefore, the solution to the equation $$\frac{3}{2}=\frac{3}{2x}-\frac{6}{5x}$$ is $x = \frac{5}{9}$ .
