I am doing this worksheet on 2 step equations. This one I have done repetedly and gotten the same answer. The answers are on the back, but I keep getting the wrong one. The correct answer is 11, but for some reason I get -1. Can anyone tell me what I'm doing wrong?
The problem is: −1=5+x/6

Your both wrong. How can I tell.
-1 not equal to 5+11/6 and
-1 is not equal to 5 + -1/6
The answer is -36
-1 = 5 + -36/6 as a check.
You should have gotten -6 = x/6 when you subtract 5 from both sides. Solve for x and you get -36.
It happens: The answer is wrong.
Thanks for attempting the problem.

Hum... I think that the actual problem is this:
-1 = \frac{5+x}{6}
Let's check your answers...
\frac{5 + (-1)}{6} = \frac46 = \frac23
Wrong.
\frac{5 + (11)}{6} = \frac{17}{6}
Wrong again...
The answer is -11. How? That's how:
-1 = \frac{5+x}{6}
Multiply throughout by 6.
- 6= 5+x
Subtract 5 from both sides:
-6 - 5 = 5 + x - 5
-11 =x
x = -11
I guess there was a printing error in the book, or you did a typo.
