Problem: 4+x=15
- Subtract 4 from both sides
4+x-4=15-4
- Refine
x = 11
You have to add the problem
Answer:
c = 25m + 40
Step-by-step explanation:
sin(π/6) is independent of x, so
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.
