Question 12438
1) {{{x - (-5/6) = 2/3}}}

 Remember, subtracting a negative quantity is the same as adding that quanitiy.

{{{x+5/6 = 2/3}}}  Subtract 5/6 from both sides.

{{{x = 2/3 - 5/6}}} Change 2/3 to its equivalent fraction of 4/6

{{{x = 4/6 - 5/6}}}

{{{x = -1/6}}}

2) To find the difference, you subtract. Let n be the number you want to find.

{{{n -(-23) = 35}}}

{{{n + 23 = 35}}} Subtract 23 from both sides.

{{{n + 23 - 23 = 35 - 23}}}

{{{n = 12}}}
