Answer:
x=2; y=-1
Step-by-step explanation:
Hello,
(1) 6x+7y=5
(2) 2x-3y=7
We multiply equation (2) by 3, it gives
6x-9y=21 and we subtract from (1)
6x-9y-6x-7y=-16y=21-5=16
So y = -1
we replace in (1) 6x-7=5 <=> 6x=7+5=12 <=> x =12/6=2
thanks

Answer:
Amy
Step-by-step explanation:
Find their amounts of cheese per serving by dividing the cups of cheese by the number of people:
Sarah:
2.5/10
= 0.25
Amy:
1.6/8
= 0.8
Since 0.8 is bigger than 0.25, Amy has more cheese per serving.
10 + 15x + x + 10
= 16x + 20
