Question 443039
Let g be the cost of grapefruit. Let o be the cost of oranges.

6g = 10o
12g + 2o = 33

6g -10o = 0
12g +2o = 33

Multiply the 1st equation by -2.

-12g +20o = 0
 12g + 2o = 33

Add the two together:

 0g + 22o = 33

 o = 3/2  = $1.50

6g = 10(1.50)
6g = 15

g = 15/6 = 5/2 = $2.50

Oranges cost $1.50
Grapefruit costs $2.50

Hope this helped!
