g = 1/3 k         This is given in the Q

then k gives 10 to g  and they are equal

g+10 = k - 10       sub in the red equation

1/3 k + 10 = k -10

2/3 k = 20

k = 30      g = 10  originally                  total   40   calendars

G=(1/3)K
(1/3)K+10=K-10
(2/3)K=20
K=30, after multiplying both sides by the reciprocal 3/2
G=10

Greg had 1/3 as many calendar to sell as Kenzo.
g = 1/3k
Get rid of fraction, multiply by 3
3g = k
The two friends decided to share the work evenly. To do that, Kenzo gave 10 calendars to Greg.
g + 10 = k - 10
g = k - 10 - 10
g = k - 20
replace k with 3g
g = 3g - 20
20 = 3g - g
20 = 2g
g = 20/2
g = 10 calendars
then
k = 3(10)
k = 30 calendars
:
What was the total number of calendars?
10 + 30 = 40
