The system of equations x+y=46 and 15x+9y=396 could be used to find the number of boxes of each item sold.

Step-by-step explanation:

Given,

Cost of one box of raspberry scones = $15.00

Cost of one box of lemon poppy seed muffins = $9.00

Total boxes sold = 46

Total revenue earned = $396

Let,

x be the number of raspberry scones sold.

y be the number of lemon poppy seed muffins sold.

According to given statement;

x+y=46 Eqn 1

15x+9y=396 Eqn 2

The system of equations x+y=46 and 15x+9y=396 could be used to find the number of boxes of each item sold.

Y=x-7 6x-6y=-7 elimination method

Archy [21]

Answer:

The system has no solutions.

Step-by-step explanation:

Let's write it in a more traditional form

$\left \{ {{x-y=7} \atop {6x-6y=-7}} \right. \\$

Try staring at it for a bit, and then realize what you are being asked: find two numbers whose difference is - at the same time, 7, and -7/6. That's impossible.

Same result you get by elimination. Multiply the first by 6 and either add or subtract - your choice the second. In either case you will get 0 = 35 or 0=49, which are obviously absurd
