Olivia has $256 to buy presents for her 3 sisters and 2 nephews. she wants to spend $10 more on each sister than she spends on each nephew. let s= the amount she spends on each sister, and n= the amount she spends on each nephew. how much (in dollars) she spend on each sister?

$57

Step-by-step explanation:

3s+2n=256

s=n+10

rewrite the second equation as s-n=10 and multiply it by 2. Then add the equations to solve for s.

3s+2n=256

2(s-n)=10*2

3s+2n=256

+

2(s-2n)=20

5s+0=276

s=57
