Answer:
x=1, y=-1. (1, -1)
Step-by-step explanation:
2x-3y=5
x+2y=-1
---------------
2x-3y=5
-2(x+2y)=-2(-1)
-----------------------
2x-3y=5
-2x-4y=2
-------------
-7y=7
y=7/-7
y=-1
x+2(-1)=-1
x-2=-1
x=-1+2
x=1
B) is my guess i am 50% sure it could be the answer
The question is incomplete:
Keith and Michelle went out to dinner. The total cost of the meal, including the tip, came to $53.70. If the combined tip came out to $9.60, and each friend spent an equal amount, how much did each friend pay not including the tip?
Answer:
Each friend paid $22.05 without including the tip.
Step-by-step explanation:
Since you know the total cost of the meal including the tip and the value of the combined tip, you can subtract the amount of the tip from the total cost and divide the result by 2 as they spent an equal amount:
$53.70-$9.60=$44.1
$44.1/2=$22.05
According to this, the answer is that each friend paid $22.05 without including the tip.
