Recently we were doing algebra in class. I got one answer but me and my friend were kinda arguing about the - s...soo what do u know! =]
The question was -y/6= 11
I figured it out to equal this and i worked it out and it equaled 11. my answer was y= -66
--66/6 = 11
BUT my friend had y=66
-66/6= -11
Which equaled -11!!!
I kept saying mine was right, can some one help sort which one is actually correct ro is its different all to gether
True or false
-y/6= 11 Help sort out me and my friends arguement =]?

✔ 最佳答案
(- y) = 66(-1) x (-y) = (-1) x 66
y = (- 66)

- y/6 = 11
y = - 11 * 6
y = - 66
Answer: y = - 66
Proof:
- (- 66)/6 = 11
66/6 = 11
11 = 11
y = - 11 * 6
y = - 66
Answer: y = - 66
Proof:
- (- 66)/6 = 11
66/6 = 11
11 = 11

-y/6=11
-y=66
y = -66
You are right.
Cheers
-y=66
y = -66
You are right.

to find out y, you need to do the inverse.
-y/6=11
11*6=66
-y=66
but lets substitute that into the equation
-66/6=-11
if obviously doesnt work so you now need to divide buy -1(-y)
-y=66 (/-1)
y=-66
tada!

-y/6= 11
multiply BOTH sides of the equation by 6:
6(-y/6) = 6(11)
-y = 66
multiply BOTH sides of the equation by - 1:
(-1)(-y) = - 1(66)
y = - 66 ANS.
Your answer is correct.

-y/6 = 11
-y = 6(11)
-y = 66
y = 66/-1
y = -66
-y = 6(11)
-y = 66
y = 66/-1
y = -66
