Heya !!
2 × -7/3 = -14/3
Let X should be added to -14/3 to get 3/7.
Therefore,
-14/3 + X = 3/7
-14 + 3X = 3 × 3/7
3X = 9/7 + 14
3X = 9 + 98/7
3X = 107/7
X = ( 107/7 × 3 )
X = 107/21.
Hence,
107/21 should be added to -14/3 to get 3/7.
2 × -7/3 = -14/3
Let X should be added to -14/3 to get 3/7.
Therefore,
-14/3 + X = 3/7
-14 + 3X = 3 × 3/7
3X = 9/7 + 14
3X = 9 + 98/7
3X = 107/7
X = ( 107/7 × 3 )
X = 107/21.
Hence,
107/21 should be added to -14/3 to get 3/7.
