Which is a correct first step for solving this equation? 4x=7+3(2x−5)

Step-by-step explanation:

The easiest first step is to remove the brackets. Other things could be done, but they are done just because you can.

4x = 7 + 3*2x - 5*3        Just to show you more, I'll keep going.

4x = 7 + 6x - 15              Combine the minus 15 and 7

4x = 6x + 7 - 15

4x = 6x - 8                     Now add 8 to both sides. It's a toss up of what to do

4x + 8 = 6x - 8 + 8

4x + 8 = 6x                    Subtract 5x from both sides

4x - 4x + 8 = 6x - 4x

8 = 2x                             Divide by 2

x = 4

The steps usually follow this order.

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
