The solution is: x= 7 and y = 2
Step-by-step explanation:
Given equations are:

Putting x = 3y+1 in equation 2 from equation 1

Subtracting 1 from both sides

Dividing both sides by 7

Putting y=2 in equation 1

Hence,
The solution is: x= 7 and y = 2

ps. no, I'm not stalking u I just clicked on the next question from your last one.
Answer:
Either x = 3, y = 2
or
(3,2) is your answer.
Step-by-step explanation:
2x +y = 8 (1)
y = - x+ 5 (2)
Put equation (2) into equation (1). Use the y value in (2) to go into the y value in (1).
2x - x+5 = 8 Combine the x values
x + 5 = 8 Subtract 5 from both sides
x + 5-5 = 8-5
x=3
Now go back to (2). Put x in for the value of -x. Watch the sign.
y = -3+ 5
y = 2
So the answer is (3,2)
Answer:
Brand D has the highest return rate so they should eliminate that one.
Step-by-step explanation:
brand A - .0481
brand B - .0307
Brand C - .0410
Brand D - .0788
1042 / 45
=23.15
You should be able to do that with a calculator though.
