Question

K - 4.8=0.32 - 5.4k answer?

Answer 1

k =4/5

Explanation:

`k - 4.8=0.32 - 5.4k\\\mathrm{Multiply\:both\:sides\:by\:}100\\k*\:100-4.8*\:100=0.32*\:100-5.4k*\:100\\\\Refine\\100k-480=32-540k\\\\Add\: 480\mathrm{\:to\:both\:sides}\\100k-480+480=32-540k+480\\\\Simplify\\100k=-540k+512\\\\\mathrm{Add\:}540k\mathrm{\:to\:both\:sides}\\100k+540k=-540k+512+540k\\\\Simplify\\640k=512\\\\\mathrm{Divide\:both\:sides\:by\:}640\\(640k)/(640)=(512)/(640)\\\\k=(4)/(5)`
