Paul and Oliver have 6 marbles altogether. Paul has 8 more marbles than Oliver. Find the number of marbles each boy has.
- Oliver
- Paul
Number of marbles that Oliver has = 1 u
Number of marbles that Paul has = 1 u + 8
Total number of marbles
= 1 u + 1 u + 8
= 2 u + 8
2 u + 8 = 6
2 u = 6 - 8 = -2
1 u = -2 ÷ 2 = -1
(a)
Number of marbles that Oliver has
= 1 u
= -1
(b)
Number of marbles that Paul has
= 1 u + 8
= -1 + 8
= 7
Answer(s): (a) -1; (b) 7
