2.<u>-1.71/5</u>+4/7x-1/5+2/5x-4/5
3.-0.342+<u>4/7</u>x-1/5+2/5x-4/5
4.-0.342+0.57x<u>-1/5</u>+2/5x-4/5
5.-0.342+<u>0.57x-0.2</u>+2/5x-4/5
6.-0.342+0.114+<u>2/5</u>x-4/5
7.-0.342+0.114+<u>0.4x-4</u>/5
8.-0.342+0.114+<u>-1.6/5</u>
9.<u>-0.342+0.114</u>+-0.32
10.<u>-0.228+-0.32=-0.548</u>
<u>i did this all in one go so......</u>
