The sum of the minuend, subtree and difference is 3 1.6, and the subtree is 2.9 less than the difference. What are the minuend, subtree and difference?
Let the minuend be x and the subtrahend be y, then the difference is expressed as X-Y and the subtrahend as X-Y-2.9.
According to the conditions, X+Y+(X-Y)=3 1.6.
X-Y-2.9=Y
So we get 2X=3 1.6 → X= 15.8.
2Y=X-2.9 → Y=6.45
So the minuend is 15.8, and the minuend is 6.45, with a difference of 9.35.
