Solve by setting up a system of linear equations with 2 variables and 2 unknowns. there were 130 faculty at a conference. if there were 18 more women than men attending the conference, how many of each gender attended the conference?

Let there are x men and y women.

there were total 130 faculty

so x+y=130(1)

If there were 18 more women than men ,

then x+18=y(2)

plugging value of y from equation (2) in equation (1)

x+x+18=130

2x=112

x=55

y=x+18=55+18=73

so there are 55 men and 73 women

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas
