toogether they have a total of 147 pictures on their iphones. How many pictures does nicky have on her iphone and how many pictures does david have on his iphone?

Answer 1

Need more information to completely answer the question.

I have seen the extra information as "David has one more picture than Nicky"

If this is the case:

David = X +1

Nicky = X

2X + 1 = 147

2X = 146

X = 73

David would have 74 pictures to Nicky's 73 pictures.

But you would set up the equation the same in any scenario.
