Question

8/x+6 +2/5x

Answer 1

7(d-5)+12=5
7d-35+12=5
7d-23=5
7d-23+23=5+23
7d=28
7d/7=28/7
d=4

Answer 2

If the problem is: (8/x)+6+(2/5x)

(8)(5)/5x+(6)(5x)/5x+(2/5x)
(40+30x+2)/5x
(30x+42)/5x
6(5x+7)/5x

Answer 3

\[multiply 2/5 by x \to get 2x/5\]
\[8/x+6+2x/5\]
\[2x/5*x/x*8/x*5/5+6*5x/5x\]
\[2x ^{2/5x+40/5x+30x/5x}\]
\[2x ^{2}+40+30x/5x\]
\[2x ^{2}+30x+40/5x\]
\[2(x ^{2})+2(15x)+2(20)\]
answer
\[2(x ^{2}+15x+20)/5x\]

Answer 4

oops screwed up after the third sentece hard to see too here is the right answer
\[2x ^{2}/5x+40/5x+30/5x\]
