Question

34k+(6.3−8.1k)÷0.9=22

Answer 1

k = 0.6

Explanation:

In this question, we need to find the value of k for the following expression. The expression is given as :

`34k+((6.3-8.1k))/(0.9)=22`

Solving LHS first,

`=34k+((6.3-8.1k))/(0.9)\\\\=(30.6k+6.3-8.1k)/(0.9)\\\\=(6.3+22.5k)/(0.9)`

i.e.

`(6.3+22.5k)/(0.9)=22\\\\6.3+22.5k=19.8\\\\22.5k=19.8-6.3\\\\k=(13.5)/(22.5)\\\\k=0.6`

So, the value of k is 0.6.
