Question

Answer 1

divide by 2 first and start with
\[|7-7x|=x+2\] or maybe
\[|7x-7|=x+2\]

Answer 2

then you have to break it in to two cases since \(|7x-7|\) is a piece wise function

Answer 3

if \(7x-7>0\) i.e. if \(x>1\) then \(|7x-7|=7x-7\)and if \(x<1\) then \(|7x-7|=-7x+7\)

Answer 4

if you want to work with the choices, check to see which ones work

Answer 5

otherwise solve
\[7x-7=x+2\]
\[6x-7=2\]
\[6x=9\]
\[x=\frac{9}{6}=\frac{3}{2}\] for the case where \(x>1\)

Answer 6

thats not a choice tho?

Answer 7

unless its d ?

Answer 8

if \(x<1\) it is
\[-7x+7=x+2\]
\[7=8x+2\]
\[5=8x\]
\[x=\frac{5}{8}\]

Answer 9

:o you get 5/8?

Answer 10

looks like it is B

Answer 11

yes thanks so much :)
