Question 935910: 36 marbles colored either red or blue. Twice the number of red marbles is 6 less than the number of blue marbles. How many red marbles are in the bag? Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! x = number of red marbles
y = number of blue marbles
---
x + y = 36
2x = y - 6
---
put the system of linear equations into standard form
---
x + y = 36
2x - y = -6
---
copy and paste the above standard form linear equations in to this solver:
