Let each number be x and y.
number 1 ----> x
number 2 ----> y
From the question we can deduce that:
x+y=43
x-y=23
We have a simultaneous equation, we now minus or add the (based on the quantity of y and x) equations and solve for the unknown.
x+y=43
x-y=23
-------
2x=66
-------
x=33
and now, we substitute the value of x into the original equation to find y
x+y=43
-------
33+y=43
-------
y=10
The numbers are 33 and 10
