noelle spent 36 dollars on books and pens .she spent 12 dollars more on books than she did on pens .how much did she spend on books?

Sagot :

Answer:

24 dollars

Step-by-step explanation:

Let x = amount spent on pens

X + 12 = amount spent on books

X + (x+12) = 36

2x = 36 - 12 = 24

X = 24 / 2 = 12

Amount spent on books

X + 12 = 12 + 12 = 24
