Hii friend,
3/7 + X + (-8/21) + 5/22 = -125/462
=> 3/7 + X - 8/21 + 5/22 = -125/462
=> 3 ×66 + 462 × X - 8 × 22 + 5 × 21 /462 = -125/462
=> 198 + 462X -176 + 105/462 = -125/462
=> 303 + 462X -176/462 = -125/462
=> 127 + 462X/462 = -125/462
=> 462(127+462X) /462 = -125
=> 127 + 462X = -125
=> 462X = -125+127
=> X = 2/462
=> X = 1/231
HOPE IT WILL HELP YOU..... :-)
