so after you distribute the numbers through what do you obtain?
Sorry I wrote the problem wrong it's 4(x+8)^-1-1=5(x+8)^-1
so we have |dw:1377570220871:dw|
Would I distribute so i get 4x+32 but then the -1 exponent is confusing me.
look up above
Yes I see now
those are equal. what happens if you have a variable raised to the - power?
for example ou have x^-1 same as 1/x
I see. To find x I think I want to multiply by 1 on each side to remove the fraction What do you think about that?
can you show me? I would multi both sides either by (5x+40) or (4x+32)
There are multiples way of solving this problem. It's what you are most comfortable with when solving for a solution to a given problem.
I'm trying to write it out but it's tricky maybe because this is my first time. The writing tool is so shaky. Still I would multiply each side by one to get 4x+32-1=5x+40 I'm sure something needs to be multiplied. I might be wrong about multiplying by one. Ultimately I'm trying to learn the right way to do it.
Yeah I understand. Hold on.
now solve for x
You see what I did there? You can probably find a common denominator on one side and then solve for x
I can show you the other way as well if you want?
Yes this makes more sense now. I'm familiar with solving x from this point. I will solve for x.
okay sounds good=)
yep, good job!
I had to solve it really quick
Yeah me too. Thank you so much. :)
How do I give you a medal or something?
so where it says best response, click it and then you give me a medal
Your welcome. Bye now. :)
