As per the given statement, we can have the expression such as: $x+y=\dfrac{2800}{7}$ and $x-y= \dfrac{2800}{5.6}$ Thus , we have two linear equations after solving theses equations we can find the two unknown variables x and y. This information is useful to find the two unknown variables x and y. Hence, The given statement does not make sense
