$x + y = 50$

$x = 50 - y$

$x - y = 20$

$50 - y - y = 20$

$- 2y = - 30$

$y = 15 \\ x = 50 - 15 = 35$

Answer 2

Let the two numbers be x and y

Given that:-

x+y=50—————)1

x-y=20-—————)2

1+2=)

2X=70

x=70/2

x=35

From 1

x+y=50

y=50-x

y=50-35

y=15

Therefore the two numbers are 35 and 15
