You must begin by isolating the x.
1. add -35 to the other side of the equation
2. divide by 8 to get x by itself
Hope this helps!
You would multiply the students by the price (12*10=120) then multiply chaperones by price (6*15=90) then add both prices together to get 210. Then you would subtract 210 from 380 to get how many boys are in the class. 380-210=170. Since each student cost 10 so you would divide 170/10=17. There would be 17 boys in your class.
I don’t understand you buddy :/
