Question

34k+(6.3−8.1k)÷0.9=22

Answer 1

We have been given an equation $34k+(6.3-8.1k)\div 0.9=22$. We are supposed to solve our given equation for k.

We can rewrite our given equation as:

$34k+\frac{6.3-8.1k}{0.9}=22$

Let us multiply both sides of equation by 0.9.

$34k\cdot 0.9+\frac{6.3-8.1k}{0.9}\cdot 0.9=22\cdot 0.9$

$30.6k+6.3-8.1k=19.8$

$22.5k+6.3=19.8$

$22.5k+6.3-6.3=19.8-6.3$

$22.5k=13.5$

$\frac{22.5k}{22.5}=\frac{13.5}{22.5}$

$k=0.6$

Therefore, the value of the k is 0.6.
