Answer 1

Answer:

$x = 27 \: and \: y = 18$

Step-by-step explanation:

l

$let \: the \: two \: numbers \: are \: x \: and \: y$

$the \: by \: given \: condition \\ \\ x + y = 45 \: \: \: < 1 > \\ x - y = 9 \: \: \: < 2 >$

$adding \: eq < 1 > \: and \: < 2 > \\ x + y = 45 \\ x - y = 9$

$2x = 54 \\ x = \frac{54}{2} \\ x = 27 \\ put \: x = 27 \: in \: eq < 2 > \\ 27 - y = 9 \\ y = 27 - 9 \\ y = 18$
