0.6+(0.5y-1)=y+0.5
What is x?

y = -1.8

Step-by-step explanation:

0.6+(0.5y-1)=y+0.5

the parenthesis can be remove because there is no multiplication

0.6 + 0.5y - 1 = y + 0.5

now combine numbers

0.6 - 1 + 0.5y = y + 0.5

-0.4 + 0.5y = y + 0.5

subtract 0.5 from both sides

-0.4 - 0.5 + 0.5y = y

-0.9 + 0.5y = y

now subtract 0.5y from both sides

-0.9 = 1y - 0.5y

-0.9 = 0.5y

now divide both sides by 0.5 and switch

y = -1.8

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
