Blackberries

Daniel, Jolana, and Stanley collected 34 blackberries together. Daniel collected eight blackberries more than Jolana, and Jolana 4 more than Stanley. Determine the number of blackberries each collected.

Final Answer:

D =  18
J =  10
S =  6

Step-by-step explanation:


D+J+S=34
D = 8 + J
J = 4 + S

D+J+S = 34
D-J = 8
J-S = 4

Row 2 - Row 1 → Row 2
D+J+S = 34
-2J-S = -26
J-S = 4

Row 3 - 1/-2 · Row 2 → Row 3
D+J+S = 34
-2J-S = -26
-1.5S = -9


S = -9/-1.5 = 6
J = -26+S/-2 = -26+6/-2 = 10
D = 34-J-S = 34-10-6 = 18

D = 18
J = 10
S = 6
