u = 6 & v=5 .

Step-by-step explanation:

Here we need to find the solution to the system: 0.5u-0.6v=0 ,0.4u+1.7v=10.9

Let's solve both equations :

⇒ 0.5u-0.6v=0

⇒ 0.5u=0.6v

⇒ $u = \frac{6}{5}v$

Putting this value in equation : 0.4u+1.7v=10.9

⇒ 4u+17v=109 { Multiplying both sides by 10 }

⇒ $4(\frac{6}{5}v )+17v=109$

⇒ $v(\frac{24}{5} +17)=109$

⇒ v(21.8)=109

⇒ v=5

Putting this value in equation : $u = \frac{6}{5}v$

⇒ $u = \frac{6}{5}(5)$

⇒ u = 6

Therefore , u = 6 & v=5 .
