Answer:
x = - y-12/5+4k
Step-by-step explanation:
<u>Solve 12-5x-4kx=y for x</u>
12-5x-4kx = y for x
substract 12 from both side
-5x-4kx = y-12
Factor of -5x-4kx = -x(5+4k)
-x(5+4k) = y-12
Solve for x
-x = y-12/(5+4k)
Therefore x = - y-12/5+4k
$1200.50
plug 5 for n
5000(.7)^4
5000*.2401
=1200.5
x+8<26
Hope this helped!
