Question 949592

W=no of women; M=no of men
1.W=3M-1 Don't see anything wrong here unless there is more to the problem.
2.x=one number, y=the other
x+y=15
x=15-y
2x=3y Substitute for x
2(15-y)=3y
30-2y=3y Add 2y to each side
30=5y
6=y ANSWER 1: The other number is 6.
x=15-y=15-6=9 ANSWER 2: One number is 9.
CHECK:
2x=3y
2(9)=3(6)
18=18
x+y=15
9+6=15
15=15
