SOLUTION :
1.
3/(x - 1) = - 3/(x+2)
Multiply by (x - 1)(x + 2) to both sides :
=> 3(x + 2) = - 3(x - 1)
=> 3x + 6 = - 3x + 3
Add 3x to, and subtract 6 from both sides :
=> 6x = - 3
Divide both sides by 6 :
=> x = - 3/6
=> x = - 1/2 (ANSWER).
2.
- 10/m + 10/7 = 4/m
Multiply by 7m , both sides :
=> - 70 + 10m = 28
Add 70 to booth sides :
=> 10m = 28 + 70 = 98
=> m = 98/10
=> m = 9.8 (ANSWER).
