4x+7y=8.77
8x+14y=15.80

Question

4x+7y=8.77
8x+14y=15.80

anonymous · Answer

If i times the first equation by -2 that gives me
-8x-14y=-17.54
8x+14y=15.80
Everything cancels out and I'm left with
-1.74

you might want to consider naming the variables something useful instead of x and y

Here's the entire question On Monday, the office staff at your school paid 
    $8.77 for 4 cups of coffee and 7 bagels
     8.77 = 4c + 7b

On Wednesday, they paid 
     $15.80 for 8 cups of coffee and 14 bagels
    15.80 = 8c + 14b
