Talia is solving the following equation.
7x - 4 = 31

Which shows a step Talia can use to solve the equation?
A.
7x - 4 = 31 + 4
B.
7x - 4 + 4 = 31 + 4
C.
7x - 4 - 4 = 31 - 4
D.
7x - 4 = 31 - 4

b, 7x-4+4=31+4

Step-by-step explanation:

you always want to start by isolating the x value, which means that you have to get rid of any outside numbers. by adding four, you are getting rife of the four. but, you have to add the four on the other side to keep it equal.

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
