Final Answer:
The value of x is approximately 262.29.
Step-by-step explanation:
Combine like terms: Add the expressions on the left side to get -7/18x = -102.
Isolate x: Multiply both sides by -18/7 to get x = (-102 * 18) / -7.
Simplify: Calculate x = 262.2857142857143 (rounded to 5 decimal places).
Therefore, x is approximately 262.29.
