Question

how:
kx+8=5x equals 8/5-k?
-4(2x+1)-(x-2)=-11 equals 1?

Answer 1

\[kx + 8 = 5x\]
subtract kx from both sides
\[\implies 8 = 5x - kx\]
factor out x..
\[\implies 8 = x(5-k)\]
then, lastly, dividie both sides by 5-k

does that help?

Answer 2

yes, what about the second one??

Answer 3

just expand it and distribute
\[\implies -8x - 4 - x + 2 = -11\]
solve for x

Answer 4

thanks :) , second one i mistakenly had -2 instead of +2 that's why i get -7/9 as an answer

Answer 5

i see
