Final answer:
The expression (8.1 + 7.9)x – (25 ÷ 5)x simplifies to (11.0)x, where you would multiply the value of x by 11.0 to get the final result.
Step-by-step explanation:
The question you asked involves evaluating an algebraic expression with a variable x. First, we simplify the expression by performing the operations inside the parentheses. The expression (8.1 + 7.9)x – (25 ÷ 5)x simplifies to (16.0)x – (5)x since 8.1 + 7.9 equals 16.0, and 25 ÷ 5 equals 5.
To finish evaluating the expression, we then combine like terms by subtracting (5)x from (16.0)x, which gives us (11.0)x. This means that for any value you substitute for x, you would multiply that value by 11.0 to get the final result of this expression.
If you were looking for a specific numerical solution for x, such as when the equation equals zero, or when solving for x using given values, additional steps would be required. However, as the question stands, no specific values have been provided, hence, we can't numerically evaluate x.
