x+y=19
x-y= 19
x-y=21​

Answer 1

Answer:

6+7+x+8+y+14=9

13+x+y+22=9

x+y=9-35

plssss complete ur question

Answer 2

Answer:

x+y=19

Step-by-step explanation:

The question is about mean, so we will divide it by the number of terms, which are six

Therefore,

$\frac{ 6+7+x+8+y+14}{6} = 9$

6+7+x+8+y+14 = 9×6

6+7+x+8+y+14 = 54

x+y+35 = 54

x+y= 54-35

x+y=19

hope it helped
