Rael and Liam have 19 balls altogether. Rael has 5 more balls than Liam. Find the number of balls each boy has.
- Liam
- Rael
Number of balls that Liam has = 1 u
Number of balls that Rael has = 1 u + 5
Total number of balls
= 1 u + 1 u + 5
= 2 u + 5
2 u + 5 = 19
2 u = 19 - 5 = 14
1 u = 14 ÷ 2 = 7
(a)
Number of balls that Liam has
= 1 u
= 7
(b)
Number of balls that Rael has
= 1 u + 5
= 7 + 5
= 12
Answer(s): (a) 7; (b) 12
