Question

Kim have 13 pencils she gave some pencils to her friend and then she got two new pencils now she has 9 pencils how many pencils did she give her friend​

Answer 1

I think she gave her friend 6 pencils 13-6= 7+2= 9

Answer 2

Kim gave her friend 6 pencils

Explanation:

If Kim had 13 pencils to start of with, then gives her friend some, gets two more and ends up with 9 that means she gave her friend 6 pencils. Since she got two more, that put her at 9, meaning she must have had 7 before then, meaning she gave her friend 6 pencils.

I hope that makes sense :)
