what do you have so far
absolute value? I don't see any absolute value bars in the original problem `3x -4=5(x-4)`
Mistake on my part.
can you draw out the full problem?
are there any vertical bars in the problem?
I made a big mistake. Hold on.
X=0 because different multiplications of X are being subtracted by 4. 3x3=9-4=5 5x3=15-4=9 5 does not equal 9. 3x0=0-4=-4 and 5x0=0-4=-4 but negative 4 equals negative 4 so the answer is X= 0?
is it possible to post a screenshot? that would clear up all confusion
The question isn't online.
oh it's on paper, I see
I'm going to assume there is no set of absolute value bars The first step is to distribute the 5 through 3x -4=5(x-4) 3x -4=5*x-5*4 3x -4 = 5x - 20 with me so far?
There are no bars. I am with you
ok now we need to move the x terms over to one side. Say the left side
subtract 5x from both sides |dw:1443246000337:dw|
notice the 5x terms cancel on the right side |dw:1443246026894:dw|
what is 3x-5x equal to?
243? Probabaly wrong. defiantly
you're just subtracting
no exponents are involved
Explain a little more? My brain is about to shut down on me lol I can barely think, im so tired.
I'm sure you know how to do 5-3 ?
think of it like that, but the result will be negative
yes I do lol
you have 3 dollars in your pocket you buy something worth $5 you'll be 2 dollars in debt
so 3x-5x = -2x
-2x - 4 = -20
now add 4 to both sides to move that 4 over
But thats not the final answer?
How do I add four to both sides? LOL ugh..
Yeah I know, I'm being a pain. But it's good to know how to do this stuff |dw:1443246705151:dw|
what would -20+4 simplify to?
it would be similar to -5+3 like you did last time
-16 actually start at -20. Then move 4 spots to the right (because of the +4)
we now have this equation -2x = -16
the last thing needed to be done is dividing -16 over -2
the two negatives divide to a positive
just like how (-2) times (-2) = +4 similar to negative times negative = positive
So its either x=8 or x=0.
0? how are you getting that?
Thats just one of the options for an answer.
ok -16/-2= 8 because a -n and -n = +n.
I kind of explained my answer for it possibly being 0 above.
X=0because different multiplications of X are being subtracted by 4. 3x3=9-4=5 5x3=15-4=9 5 does not equal 9. 3x0=0-4=-4 and 5x0=0-4=-4 but negative 4 equals negative 4 so the answer is X= 0
well when you said -8, you were close but it's actually +8 or just 8 since negative/negative = positive
Final answer 8?
