Looks like a whole lot of fun you got there... Okay.. so first you'd have to add up the two values on the left side by multiplying the top and bottom of the first by the denominator of the second and by multiplying the top and bottom of the second by the denominator of the first, like this (sorry for all the parentheses) :
[x(x-4)]/[(x+4)(x-4)] + [4(x+4)]/[(x+4)(x-4)]. now you can add them together:
[x(x-4)+4(x+4)]/[(x+4)(x-4)] then i'd try to combine the top:
x^2-4x+4x+16 or x^2+16, then i'd combine the bottom (since i just noticed something awesome here):
x^2-4x+4x-16 or x^2-16. This makes the left side look exactly like the right ( isn't that awesome!) This means x = 1!
Answer:
$148.50
Step-by-step explanation
I solved this by using fractions.
x/450=33/100 is how I set up the problem. 33/100 represents 33%, while x/450 represents how much the jacket costs now.
I then went across and multiplied x by 100, and 450 by 33, which gave me 100x=14850. After this I divided each side by 100 to get 148.5, being the cost of the jacket.
Multiply the original price by the decimal form of the percent and subtract that from the original price.
77*0.85=65.45
77-65.45=11.55
Answer: New price is $11.55
