Question

2/3x-3/4x+4/5x=2/15​

Answer 1

Answer:

Step-by-step explanation:

take lcm 60

40 x - 45 x - 48 x 60 = 2/15

-53 x / 60 = 2/15

- 795 x = 120

x = -120/795

Answer 2

SOLUTION:-

Given:

2/3x - 3/4x + 4/5x = 2/15

Therefore,

$= > \frac{2}{3} x - \frac{3}{4} x + \frac{4}{5} x = \frac{2}{15} \\ [Take \: L.C.M. \: of \: 3 ,4 ,5] \\ \\ = > \frac{40x - 45x + 48x}{60} = \frac{2}{15} \\ \\ = > \frac{43x}{60} = \frac{2}{15} \\ [Cross \: multiplication]\\ \\ = > 15 \times 43x = 60 \times 2 \\ \\ = >645x = 120 \\ \\ = > x = \frac{120}{645} \\ \\ = > x = \frac{24}{129} \\ \\=>x=\frac{8}{43}$

Hope it helps ☺️
