Ateacher has a box of pens and pencils. there are 8 more pencils than pens. after the students take 1 pen and 5 pencils from the box, there are 26 pens and pencils left in a box. how many pens are in the box now? how many pencils?

Let no. of pens be x.

Pens : x
Pencils: x+8

Total: 2x+8

Student takes 1 pen and 5 pencils.

Remainder: 2x+8 - 5 -1 = 2x+2
2x+2 = 26
2x= 24
x = 12 (original no. of pens)
x+ 8 = 20 (original no of pencils)

There are 12 pens at first and 20 pencils.
After 1 pen is taken, 11 pens are left.
After 5 pencils are taken, 20-5=15 pencils are left.
