Let the age of devaughn be x and Sydney be y. Then,x+y=45 x+5=y y=x+5 here, put y=x+y in x+y=45 then, x+y=45 x+x+5=45 2x=40 x=20 now, y=x+5 y=20+5 y=25
total age=45 devaughn is 5 years younger 45-5=40 so , 40 divided by 2 equals= 20 so each of them is 20 without remaining 5 so devaughn is 20 so sydney is 45-20=25 so, sydney is 25 years old
