Question

What is the value of x? Justify each step.

Answer 1

???

You just posted the steps AND the solution!!!

Answer 2

Yes I am a bit confused here as to what the response is supposed to be for the homework. Perhaps the names of the steps?

Answer 3

I REALLY have no idea what your teacher wants here.

And I also have no idea on earth why that "AB + BC = AC" thingy is included. It has absolutely nothing to do with solving for x.

As for "naming the steps", I suppose that you might try:
b. combine x terms
c. subtract 8 from both sides
d. divide both sides by 8
e. Yo answer yo!

But beyond that, I haven't a clue... :-(

Answer 4

well the whole AB + BC = AC is referring to the second picture, saying that if you add the two line segments you get AC (the entire line)

Answer 5

AB = 2x
BC = 6x + 8

if AC = 32, it wants you to find x

which means 2x + 6x +8 = 32

the 2x and the 6x add together to make 8x +8 = 32

subtract 8 from both sides

8x = 24

divide by 8 on both sides

x = 3

Answer 6

Ahh so!!

The link shows no picture, only 5 equations labeled a-e, with the ab+bc=ac being the "a" line.

Answer 7

i see 2 links:

1 with the steps, and 1 with a picture

Answer 8

So do I just justify each step by naming them and then state the value of x?

Answer 9

Gak!!! You're right!! I missed the second one (obviously)... :-(

But even still, the answer is already posted, along with the steps, so I can't tell what the teacher wants.

Answer 10

@Usagi18

for example, to justify the 2nd step, you must subtract 8 from BOTH sides so that it is equal on both sides of the equal sign. (that's why there is an equal sign to begin with haha)
