Answer:
First number is 12
Second number is -1
The smaller of the two numbers is the second number.
The larger of the two numbers is the first number.
Explanation:
let a = first number and b = second number
a + 2b = 10 eq.1
2a + b = 23 eq.2
multiply equation 2 by -2 to eliminate b
-2(2a + b = 23)
-4a - 2b = -46 eq.3
add equations 1 and 3
a + 2b = 10
-4a - 2b = -46
____________
-3a = -36
a = 12
substitute a = 12 to any of the equations
I use equation 1
a + 2b = 10
12 + 2b = 10
2b = -12
b = -1
