Question

Carla was going to sell all her stamps collection to buy a video game. after selling half of them she changed her mind. she then brought four more. how many did she start with if she now has 26?

Answer 1

Formulating an equation that represents the situation, we have:

1/2*x + 4 = 26 (x represents the initial number of stamps)

1/2*x = 26 - 4 (Subtracting 4 from both sides of the equation)

1/2*x= 22 (Subtracting)

x= 22 / (1/2) (Dividing by 1/2 on both sides of the equation)

x= 44 (Dividing fractions)

The answer is 44 stamps.
