Follow PEMDAS: First, we need to follow the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). This is often remembered by the acronym PEMDAS. In the expression 5x−10÷2, we have multiplication (5x), division (10÷2), and subtraction. According to PEMDAS, we should perform the division before the subtraction.
Perform Division: Perform the division 10÷2, which equals 5.Calculation: 10÷2=5
Substitute Result: Now, substitute the result of the division back into the expression to get 5x−5.
Simplify Expression: Since we cannot simplify the expression further without knowing the value of x, the simplified expression is 5x−5.
