Answer:
X=-3/8 (x equals negative 3 over 8.)
Step-by-step explanation:
So, you have twice a number and six. That is going to be 2x*6, and that then simplifies into 12x. Now, 11 times the number, would be 11x. The difference between 11x and 3/8 would be 11x-3/8.
So, You now have 12x=11x-3/8.
Combine like factors. So, 12x-11x=-3/8.
Now, you have x=-3/8.
Hope this Helps!! (:

<span>the line over the 28 means the 28 repeats forever.
1.282828.... and so on
let x be the rational number 1.28...
we can use this trick:
100*1.282828....= 128.282828... (the decimal 28 part repeats)
100x = 128.28...
next:
100x - x = 128.282828... - 1.282828...
the .282828... part will be subtracted away
99x = 127
divide both sides by 99 to get
x= 127/99</span>
