Algebraic Expression Explanation:
An algebraic expression is a mathematical phrase that can contain numbers, variables, and operations such as addition, subtraction, multiplication, and division. In the given expression 2p-3=7, we have a variable 'p' along with constants and operations.
- Variables and Constants: In this expression, 'p' is the variable representing an unknown value, while 2, 3, and 7 are constants representing specific numbers.
- Operations: The expression involves the subtraction operation (-) to combine the terms 2p and 3, resulting in 7 on the right side of the equation.
- Equation: The expression is in the form of an equation, where the left side (2p-3) is equal to the right side (7). This equation can be solved to find the value of the variable 'p' that satisfies the equality.
- Solving the Equation: To solve the equation 2p-3=7, you would need to isolate the variable 'p' by performing inverse operations. In this case, you would add 3 to both sides of the equation to get 2p=10, and then divide by 2 to find that p=5.
In conclusion, the expression 2p-3=7 is an algebraic expression that involves variables, constants, and operations, and it can be solved to determine the value of the variable 'p' that satisfies the equation.
