1. Given s = 3x +t/r rearrange the equation for x, in terms of r, s, and t
2. Given 5ax + b = C, rearrange the equation for x, in terms of a, b, and c.

Step-by-step explanation:

1). s =

   r.(s) =

   rs = 3x + t

   rs - t = 3x

2). 5ax + b = c

   (5ax + b) - b = c - b

   5ax = c - b

    x =

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

the two may have that, even a breakdown is probably offered
