Together m+w

Women are 30%. Men are 360 more.
How many are together?

Final Answer:

s =  900

Step-by-step explanation:


s=m+z
z = 0.30 s
m = 360+z

s=m+z
z = 0.30·s
m = 360+z

m-s+z = 0
0.3s-z = 0
m-z = 360

Row 3 - Row 1 → Row 3
m-s+z = 0
0.3s-z = 0
s-2z = 360

Pivot: Row 2 ↔ Row 3
m-s+z = 0
s-2z = 360
0.3s-z = 0

Row 3 - 0.3 · Row 2 → Row 3
m-s+z = 0
s-2z = 360
-0.4z = -108


z = -108/-0.4 = 270
s = 360+2z = 360+2 · 270 = 900
m = 0+s-z = 0+900-270 = 630

m = 630
s = 900
z = 270
