Question

For the variables x and y, the two
regression lines are 6x + y = 30 and
3x + 2y = 25. What are the values of
x, y and r respectively ?​

Answer 1

Answer:

Y = 10

X = 20/3

Step-by-step explanation:

6x + y = 30

or, y = 30 - 6x

so,

3x + 2y = 30

or, 3x + 2(30 - 6x) = 30

or, 3x + 60 - 12x = 30

or, 9x = 60 - 30

or x = 30/9

or, x = 10/3

6x + y = 30

or, 6 X 10/3 + y = 30

or, 60/3 + y = 30

or, 20 +y = 30

or y = 10
