The presentation

The travelers' presentation came with three times as many men as women. When eight men left with their partners, there were five times more men than women at the presentation. How many were men and women originally?

Correct answer:

m =  48
z =  16

Step-by-step explanation:

m=3z
m-8 = 5·(z-8)

m=3·z
m-8 = 5·(z-8)

m-3z = 0
m-5z = -32

Row 2 - Row 1 → Row 2
m-3z = 0
-2z = -32


z = -32/-2 = 16
m = 0+3z = 0+3 · 16 = 48

m = 48
z = 16
