X +y = 5
x = 5-y
---------------------
2x -y = 1
2•(5-y) -y = 1
10 -2y -y = 1
10 -3y = 1
-3 y = 1-10
-3y = -9
then you can divide it
y = -9/-3
y= 3
for x :
x + y = 5
x + (3) = 5
x= 5-3
x= 2
(x,y)
(2,3)
She must mix 1.5 cups of pineapple juice into the pitcher.
Since Cindy is making a fruit juice drink, and the recipe calls for 5 parts apple juice and 3 parts pineapple juice, and Cindy puts 2 1/2 cups of apple juice into a pitcher, and Cindy wants the juice drink in her pitcher to taste the same as the drink in the recipe, to determine how much pineapple juice does she need to mix into the pitcher, the following calculation must be performed, proposing a cross multiplication:
- 5 = 2 1/2
- 3 = X
- 5 = 2.5
- 3 = X
- 3 x 2.5 / 5 = X
- 7.5 / 5 = X
- 1.5 = X
Therefore, she must mix 1.5 cups of pineapple juice into the pitcher.
