1,398 * 4 = 5,592
5,592/3 = 1,864
Each pile would have 1,864 legos.
- 
+ 6
divide each term on the numerator by 7b
= - 7
/ 7b + 42 / 7b
= - + 6
I believe its 20% salt to water ratio since theres 5 pieces all together
X is cheeseburgers and y is hamburgers
x + y= 351
2x+y=351
Now I can do 351 divided by 3 which gives me 117. Since 117+117+117 is 351 and the number of cheeseburgers sold was twice the amount as hamburgers. I will say that there was 117+117 cheeseburgers sold and there were 117 hamburgers sold.
Hope it makes sense.....
