How do i isolate x in 4x - 2y = 22?

4x - 2y = 22

Start by adding 2y to both sides

4x = 22 + 2y

now divide by 4

x = 22/4 + 2y/4

Reduce to get

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
