Mary has twice as many pencils as she has pens. Tom borrows a pen. Now, Mary has ten less pens than pencils. How many pencils does Mary does?

Answers

Answer 1

Answer: x - the number of pencils
y - the number of pens

She has twice as many pencils as she has pens.
$x=2y$

Tom borrows a pen, so she has y-1 pens. Now she has ten less pens than pencils.
$x-10=y-1 \nx=y-1+10 \nx=y+9$

Set 2y and y+9 equal to each other:
$2y=y+9 \n2y-y=9 \ny=9$
She has 9 pens.
