Question

2 X upon 5 minus 3 x upon 4 =3/10

Answer 1

here you go ☆☆

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

▪$\frac{8x - 15x}{20} = \frac{3}{10}$ (taking 20 as LCM)

▪$\frac{ - 7x}{20} = \frac{3}{10}$

▪$- x = \frac{3}{10} \times \frac{20}{7}$

▪$- x = \frac{6}{7}$

▪$x = - \frac {6} {7}$

hope it helps you.......

Hello ,

Your answer is given below
Plz mark it as the BRAINLIEST
$\frac{2x}{5} - \frac{3x}{4} = \frac{3}{10}$
The L.C.M. of 5 and 4 is 20. So,
$\frac{4(2x) - 5(3x)}{20} = \frac{3}{10} \\ \frac{8x - 15x}{20} = \frac{3}{10}$
By cross multiplication,
$10( - 7x) \: = 60 \\ - 70x = 60$
$x = \frac{60}{ - 70} = \frac{ - 6}{7}$
Hope it helps you... :-)
