Answer:
The integers are 9 and 22
Step-by-step explanation:
Step one:
given data
let the smaller integer be x
and the bigger be y
x+y=31-----------1
so
y=(2x+4)
Step two:
put y=(2x+4 in equation 1 we have
x+2x+4=31
3x+4=31
3x=31-4
3x=27
divide both sides by 3
x=27/3
x=9
the smaller integer is 9
the bigger is 2(9)+4= 18+4=22
