15 16

Answer 1

Answer:

Let

$a + b = 14 \\ + \: \: \: + \\ c - d = 10 \\ - - - - - - \\ 15 \: \: 16$

From these equation

$b = 14 - a \\ d = 16 - b = 16 - 14 + a = 2 + a \\ c = 15 - a$

Finally

$c - d = 10 \\ 15 - a - 2 - a = 10 \\ 2a = 3 \\a = \frac{3}{2} = 1.5$

And others

$b = 12.5 \\ c = 13.5 \\ d = 3.5$
