Answer 2

To solve the equation:

-х - (-2 1/2 + 5 3/4) = -5 5/6

You can start by simplifying the expression inside the parentheses on the left side of the equation:

-х - (-2 1/2 + 5 3/4) = -5 5/6

Now, let's simplify the expression inside the parentheses:

-х - (-2 1/2 + 5 3/4) = -5 5/6

First, add the fractions:

-х - (-2 1/2 + 5 3/4) = -5 5/6

-х - (-2/2 + 23/4)

Now, find a common denominator, which is 4:

-х - (-4/4 + 23/4)

Now, subtract the fractions:

-х - (19/4)

Now, let's simplify the right side of the equation:

-5 5/6 = -6 1/6

Now, rewrite the equation with the simplified expressions:

-х - (19/4) = -6 1/6

Next, add 19/4 to both sides of the equation to isolate -x:

-х - (19/4) + (19/4) = -6 1/6 + (19/4)

This simplifies to:

-х = -6 1/6 + 19/4

Now, find a common denominator to add the fractions on the right side:

-х = -37/6 + 19/4

To add these fractions, you need a common denominator, which is 12:

-х = (-37/6) * (2/2) + (19/4) * (3/3)

-х = (-74/12) + (57/12)

Now, subtract the fractions:

-х = (-74 + 57)/12

-х = -17/12

Now, you have the value of -x:

-х = -17/12

To solve for x, multiply both sides by -1 to isolate x:

x = 17/12

So, the solution to the equation is:

x = 17/12
