Word problems starter
Callum has a collection of badges. His aunt gives him 9 more badges. Then, during carnaval break, Callum collected enough to double his collection. He now has 132 badges in total. How many badges did Callum have to start with?
1. 2(x + 9) = 132
2. 2x + 18 = 132
2x = 114
x = 57
Callum had 57 badges to start with
