It is -7/2 when the variables are substituted
36 because in total there are 46, 20 playing football, 16 playing hockey and 10 who plays both so if you add 20+16+10 you get 46, but then you take away the 10 who play both to get an answer or 36 students
idk this a really hard problrm
6x(-3)= (-5x) + 7
-18x = -5x + 7
-18x + 5x = 7
-13x = 7
x = 7/-13
x= -7/13
