“If 54 is subtracted from three times a number yielding 36 what is the number?”

"To find the number solve 3x - 54 = 36 where x is the unknown. Adding 54 to both sides gives 3x = 90 and dividing by 3 yields x = 30. This linear equation models real-world problems like budgeting. Understanding such equations enhances problem-solving skills applicable in mathematics and everyday decision-making scenarios."
