Can someone explain me where this 13 came from, please? (sorry my poor english i'm brazilian)
Alekssandra [29.7K]

Hey there,

a-7=3(b+2), we do 3 times b and 3 times 2 according to the rule.

a-7=3b+6 we change + to - and - to + when move nums from 1 side to another one.

a=3b+13 we get the solution.

Hope this helps :)
