Aliyah 7 pencils and a notebook. the notebook cost $4. she spent total of $24. write an equation to determine how much each pencil cost? I need help

Of the $24, she has $10 left, therefore, she spent $14 on the 7 pencils. You can tell now how much each pencil cost, since 7 goes into 14, 2 times. The answer is the cost for each pencil= $2.

The right answer should be 6 but your not very specific
