Question 937034: Makayla has a collection of 20 rare coins. This is 6 more than one half as many coins as Axel. How many rare coins does Axel have? Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! x = number of coins makayla
y = number of coins axel
---
x = 20
x = y/2 + 6
---
put the system of linear equations into standard form
---
x = 20
2x - y = 12
---
copy and paste the above standard form linear equations in to this solver:

answer:
x = number of coins makayla = 20
y = number of coins axel = 28
---
now by substitution:
---
x = 20
2x - y = 12
2*20 - y = 12
2*20 - 12 = y
y = 2*20 - 12
y = 28
---
answer by substitution:
x = number of coins makayla = 20
y = number of coins axel = 28
