The answer is C. The explanation in the previous comment section is correct
X - (9x - 10) + 11 = 12x + 3(-2x +

) equals
x = 
.
First, simplify brackets. / Your problem should look like: x - 9x + 10 + 11 = 12x + 3(-2x +

).
Second, simplify x - 9x + 10 + 11 to -8x + 10 + 11. / Your problem should look like: -8x + 10 + 11 = 12x + 3(-2x +

).
Third, simplify -8x + 10 + 11 to -8x + 21. / Your problem should look like: -8x + 21 = 12x + 3(-2x +

).
Fourth, expand. / Your problem should look like: -8x + 21 = 12x - 6x + 1.
Fifth, simplify 12x - 6x + 1 to 6x + 1./ Your problem should look like: -8x + 21 = 6x + 1.
Sixth, add 8x to both sides. / Your problem should look like: 21 = 6x + 1 + 8x.
Seventh, simplify 6x + 1 + 8x to 14x + 1. / Your problem should look like: 21 = 14x + 1.
Eighth, subtract 1 from both sides. / Your problem should look like: 21 - 1 = 14x.
Ninth, simplify 21 - 1 to 20. / Your problem should look like: 20 = 14x.
Tenth, divide both sides by 14. / Your problem should look like:

= x.
Eleventh, simplify

to

. / Your problem should look like:

= x.
Twelfth, switch sides. / Your problem should look like: x =

which is your answer.
x + x + 1 + x + 2 + x + 3 = 130
Combine like terms.
4x + 6 = 130
Subtract 6 from both sides.
4x = 124
Divide both sides by 4.
x = 31

Answer:
9 days
Step-by-step explanation:
He sets his watch 12 seconds behind
For every day that passes it falls back another 1 second
So once it is 21 seconds behind all you have to do is subtraction to find the amount of days past
21 - 12 = 9
Since its 12 seconds behind already itll take 9 days to be behind 9 more seconds.
