Final answer:
The mathematical expression representing 'a number multiplied by 5, subtracted from the sum of 14 and eight times the number' is simplified to 14 + 3n, where n is the number in question.
Step-by-step explanation:
The question involves a mathematical expression and the operation of basic arithmetic. We can represent the problem with the variable n for the number referenced. The expression given is 'a number multiplied by 5, subtracted from the sum of 14 and eight times the number.' To translate this into an algebraic expression, we first write the sum of 14 and eight times the number as 14 + 8n. Then we subtract five times the number from this sum, which gives us the algebraic expression 14 + 8n - 5n. Simplifying the expression, we combine like terms (the ones involving n), yielding 14 + 3n. This is a linear expression that represents the operation described.
