Emma had some pens at first. She gave 16 of her pens to her cousin and 14 of her pens to her buddy. After that, her mother gave her another 8 pens. She had 43 pens in the end. How many pens did Emma have at first?
Fraction of pens left after giving to her cousin and her buddy

16 -
14 = 1 -
212 -

712 Number of pens left after giving to her cousin and her buddy = 7 u
Number of pens left after her mother gave her another 8 pens = 7 u + 8
7 u + 8 = 43
7 u = 43 - 8
7 u = 35
1 u = 35 ÷ 7 = 5
Number of pens that Emma had at first
= 12 u
= 12 x 5
= 60
