Im stuck after
x+y=48
.29x+.51y=? Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! x = pounds of 29% alloy
y = pounds of 51% alloy
---
x + y = 48
29x + 51y = 50*48
---
put the system of linear equations into standard form
---
x + y = 48
29x + 51y = 2400
---
copy and paste the above standard form linear equations in to this solver:
