having difficulty trying to establish the answer i think it's 13792

Question

for every 3 aliens that visited planet earth from mars, 5 aliens from venus visited planet earth. if 55168 total aliens visited earth last year, determine the number of aliens from mars that visited earth.

Answer 1

mars     venus

3          5                 3+5=8

6          10                6+10=16

9          15                9+15=24

as you can see this method is way too time-consuming

let x=the number to multiply both 3 and 5 by

3x+5x=55,168

8x=55,168

x=55,168/8

x=6896

3x=3*6896=20,688 aliens from mars
