Lulu used these steps to solve the equation 8x−2=2(4x−2)8x-2=2(4x-2). which choice describes the meaning of her result, -2=-4-2=-4?
a. the solution is -4-4.
b. no values of xx make the equation true.
c. all values of xx make the equation true.
d. the result is not correct because step 22 has an error.

Option B is correct.

No value of x make the equation true

Step-by-step explanation:

Given the equation:

8x - 2 = 2(4x - 2)

Using distributive property i.e

8x -2 = 8x - 4

Subtract from both sides by 8x we get;

8x - 2 -8x = 8x - 4 -8x

Simplify:

-2 = -4              no solution.

It is impossible for the equation to be true no matter what value we assign to the variable x.

therefore, no value of x make the given equation true.

Also, you can see in the graph shown below.

step-by-step explanation:

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7  

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
