a group of 48 students attend a baseball game. the number of women is 12 more than the men. how many men and women attended the game

First, identify your variables:

Let x = number of men in attendance.

Let y = number of women in attendance.

x + y = 48.

and

y = 12 + x

sub the second equation in for y in the first equation:

x + (12 + x) = 48.

12 + 2 x = 48

2 x = 36

x = 18

y = 12 + 18

y = 30
