Answer 2

The value of x is equal to $\frac{-6}{7}$.

Step-by-step explanation:

We are given,

$\frac{2x}{5} -\frac{3x}{4} =\frac{3}{10}$

• Solving given equation,

First of all we have to take L.C.M of L.H.S,

L.C.M of 5 and 4 is 20.

$\frac{2x}{5} -\frac{3x}{4} =\frac{3}{10}$

$\frac{4*2x-5*3x}{20} =\frac{3}{10}$

$\frac{8x-15x}{20} =\frac{3}{10}$

Taking 20 from L.H.S to R.H.S, we get

$8x-15x=\frac{3}{10}*20$

$-7x=3*2$

$-7x=6$

$x=\frac{-6}{7}$

we get the answer of this question as $x=\frac{-6}{7}$.
