Here's a more simple way

 

Amount spent on each nephew = N

Amount spent on  each  sister= N + 10

 

So

 

2N  + 3(N + 10) = 180     simplify

 

2N + 3N + 30   =180       subtract  30 from both sides and simplify the left side

 

5N  = 150    divide both sides by  5

 

N = $30   = amt spent on each nephew

 

N + 10 = $ 40  = amt spent on each sister

 

 

cool cool cool
