Final answer:
To find the value of X, subtract -1/2 from both sides of the equation and simplify to get x = -19/4..
Step-by-step explanation:
To find the value of X, we need to isolate it on one side of the equation. We can do this by subtracting -1/2 from both sides of the equation:
x = -21/4 + 1/2
Simplify the right side of the equation by finding a common denominator for -21/4 and 1/2, which is 4:
x = -21/4 + 2/4
Combine the numerators:
x = -19/4
Therefore, the value of X is -19/4.
