Nikola and Agáta received a total of 20 roses from their partners. Nikola received 4 more roses than Agáta. How many roses did each have?

Correct answer:

a =  8
n =  12

Step-by-step explanation:


n+a=20
n=4+a

a+n = 20
a-n = -4

Row 2 - Row 1 → Row 2
a+n = 20
-2n = -24


n = -24/-2 = 12
a = 20-n = 20-12 = 8

a = 8
n = 12
