Question 853841
we have two equations, let x be one positive integer and y be the other
 x +  y =  9
2x + 3y = 22
solve first equation for x and substitute in second equation
x = 9 - y
2(9-y) +3y = 22
18-2y +3y = 22
y = 4
x = 5
substitute in second equation
2*5 + 3*4 = 22
22 = 22
our answer checks   :-)
