Để giải phương trình trên, ta cần tìm giá trị của x.

Đầu tiên, ta tính tổng của các phân số bên phải:

-23/33 + (-5/2) - 10/33 = -23/33 - 15/6 - 10/33
= -23/33 - 90/33 - 10/33
= -123/33

Simplifying the right side of the equation, we get:

-23/33 + (-5/2) - 10/33 = -123/33

Now, we can rewrite the equation as:

4 + 1/2 + x = -123/33

Next, we convert 4 to a fraction with a common denominator of 2:

4 = 8/2

Now, we can rewrite the equation as:

8/2 + 1/2 + x = -123/33

Combining the fractions on the left side, we get:

9/2 + x = -123/33

To solve for x, we need to find a common denominator for 2 and 33, which is 66:

(9*33)/(2*33) + x = -123/33

297/66 + x = -123/33

Now, we can simplify the left side of the equation:

297/66 = 99/22

99/22 + x = -123/33

To solve for x, we need to find a common denominator for 22 and 33, which is 66:

(99*3)/(22*3) + x = -123/33

297/66 + x = -123/33

Now, we can simplify the left side of the equation:

297/66 = 99/22

99/22 + x = -123/33

To solve for x, we need to isolate x on one side of the equation. Subtract 99/22 from both sides:

x = -123/33 - 99/22

To add the fractions on the right side, we need to find a common denominator, which is 66:

x = -146/66 - 198/66
x = -344/66

Therefore, the value of x is -344/66.
