Answer:

-16/35

Step-by-step explanation:

To know tha answer for this, you have to find the prime factor of 15 and 21:

Prime factor of 15: 3, 5

Prime factor of 21: 3, 7

Therefore, the LCD (least common denominator) of 15 and 21 are: 3 * 5 * 7 = 105

-14/15+10/21  

= -14*7/15*7 + 10*5 / 21*5

= -98/105 + 50/105

= -48/105

Simplify:

= -16/35
