3*boys=2*18
3*boys=36
boys=12
12+18=30
total number of students: 30
13 factored out is 13x - 39 add 39 to both sides it equals 13x=78 and 78 divided by 13 is 6 the anwser is x=6
multiply the number by show in the diagram and you need to think that your number to multiply them till you get your answer
