Question

5)
6)
If 5x + 7y = 17 & 7x + 5y = 19 then find the value of (x + y)
Find the mode of the data given below.
82,54, 65, 54, 54, 65, 82. 50. 54​

Answer 1

Answer:

x+Y=3

mode = 54

Step-by-step explanation:

5x +7y=17 ---- (1)

7x+5y=19 ----(2)

from equation (1), we have

Y=(17-5x)/7

now put this value of y in equation (2),then we have

x=2

now put this value of x in any equation ,we get

Y=1

x+Y= 2+1=3
