Answer 1

$Given : \frac{3x - 2}{10} - \frac{x+3}{7} + \frac{4x - 7}{3} = x - 1$

$= > \frac{3x - 2}{10} - \frac{x + 3}{7} + \frac{4x - 7}{3} - x = -1$

LCM of 10,7 3,3 = 210

$= > \frac{(3x - 2) * 21 - (x + 3) * 30 + (4x - 7) * 70 - 210x}{210} = -1$

$= > \frac{63x - 42 - 30x - 90 + 280x - 490 210x}{210} = -1$

$= > \frac{103x - 42 - 90 - 490}{210} = -1$

$= > \frac{103x - 622}{210} = -1$

⇒ 103x - 622 = -210

⇒ 103x = -210 + 622

⇒ 103x = 412

⇒ x = 412/103

⇒ x = 4.

Therefore, the value of x = 4.

Hope this helps!
