Find an ordered pair $(x,y)$ that solves the system:

\begin{align*} 2x - 3y &= -3.2 - 0.2x + 0.1y,\\ x &= 0.6x - y + 8.8 \end{align*}

Tidy up both equations independently.   

 

Then solve them simultaneously,

I used the elimination method and the answer got was very tidy. (no horrible decimals)

 

note that I have not checked my answer though.

 

Can you have a go at it now?
