Hi! This is my first time helping someone so I hope this helps!
X=1
Y=5
First in the first equation, subtract x on both sides.
Y= 6-x
Then substitute that into the second equation.
-3x + 6-x = 2
-4x + 6= 2
-4x = -4
x= 1
Substitute it to the first equation
Y= 6-1
Y= 5
X= 1
Hope this helps. I hope you have a great day!
Let x = pounds of $12 per pound coffee
then
20-x = pounds of $9 per pound coffee
.
12x + 9(20-x) = 10(20)
12x + 180 - 9x = 200
3x + 180 = 200
3x = 20
x = 20/3
x = 6 and 2/3 pounds of $12 per pound coffee
.
Amount of $9 per pound coffee:
20-x = 20-20/3 = 60/3 - 20/3 = 40/3
or
13 and 1/3 pounds of $9 per pound coffee
