Let the two numbers be x and y.
Given,
x + y = 23
x = 23 - y
Also given,
y = 2x - 1
y= 2(23 -y) -1
y = 46 - 2y - 1
3y = 45
y = 15
x = 23 - y = 23 - 15 = 8
Hence, the two numbers are 15 and 8.

x + y = 23
x = 2y-1
y + 2y-1 =23
3y-1 =23
3y =24
y = 24/3 =8
y = 8
x = 2*8-1 = 15
15+8 = 23
the 2 numbers are 8 & 15
