anonymous · Answer

to get an exact value, convert the answer into a fraction

anonymous · Answer

x = -759/10
y = 26/10
-x = 759/10
-xy = 759/10 x 26/10
-xy = 19734/100
- xy = 9867/50

-xy=-(-75.9*2.6)= 197.34

^^^ that is not exact form

anonymous · Answer

it doesn't look like he understood what you did. so maybe he is on a lower class then you thought. but yeah your method is the correct one if he wants exact form

anonymous · Answer

yeah so to get an exact value, simply multiply 197.34 by 100 and you get 19734/100. simplify and you will get 9867/50
