(3x+12)+x=180 Find the value of x.

x =42

Step-by-step explanation:

(3x+12)+x=180

Combine like terms

4x +12 = 180

Subtract 12 from each side

4x +12-12=180-12

4x = 168

Divide by 4

4x/4 =168/4

x =42

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
