koban [17]

So
if x is the number she spent on each sister and y is the number she spent on each nephew then
180=3x+2y

she wants to spend 15 dollars more on sisters than nephews

we have
180=3x+2y and
x=15+y
subsitute 15+y for x

180=3(15+y)+2y
180=45+3y+2y
180=45+5y
minus 45 both sides
135=5y
divide both sides by 5
27=y

solve for x
x=15+y
x=15+27
x=42

she spent $42 on each sister
