me . i'm confused on how to do elimination. this is algebra 2

solve the systems using elimination

1) 8x - 6y= -20
-16x + 17y = 30

2) -4y - 11x = 6
20= -10x - 10y

1. y = 8/11x + 10/11

2. y = -3/2x - 13/7

Step-by-step explanation:

1. -8x + 11y = 10

Add 8x to both sides

11y = 8x + 10

Divide both sides by 11

y = 8/11x + 10/11

2. 6 = -4y - 11x

20 = -10x - 10y

26 = -14y - 21x

Add 21x to both sides

-14y = 21x + 26

Divide both sides by -14 and simplify!

y = -3/2x - 13/7

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

two data sets with the same median will not have the same varaibility
