Dividing money

Vilem, Cenek, and Edita divided the money they earned by spreading the leaflet. Vilem got 240 CZK more than Cenek and twice as much as Edita. Edita got 400kc less than Vilem. How much did each of them earn?

Correct answer:

C =  560
V =  800
x =  400
s =  1760 Kc

Step-by-step explanation:


V=240+C
V = 2x
x = V-400

V=240+C
V = 2·x
x = V-400

C-V = -240
V-2x = 0
V-x = 400

Row 3 - Row 2 → Row 3
C-V = -240
V-2x = 0
x = 400


x = 400/1 = 400
V = 0+2x = 0+2 · 400 = 800
C = -240+V = -240+800 = 560

C = 560
V = 800
x = 400
