Solving the Equation: (4m + 9) - 3(2m - 5) = ?
This article will guide you through the steps of solving the equation (4m + 9) - 3(2m - 5) = ?.
Understanding the Equation
The equation involves simplifying an expression with variables and constants. We need to follow the order of operations (PEMDAS/BODMAS) to solve it correctly:
- Parentheses/Brackets
- Exponents/Orders
- Multiplication and Division (from left to right)
- Addition and Subtraction (from left to right)
Solving the Equation Step-by-Step
-
Distribute the -3:
- (4m + 9) - 3(2m - 5) = (4m + 9) - 6m + 15
-
Combine like terms:
- (4m - 6m) + (9 + 15) = -2m + 24
Therefore, the simplified expression is -2m + 24.
Conclusion
By following the order of operations, we have successfully simplified the equation (4m + 9) - 3(2m - 5) to -2m + 24. This process demonstrates the importance of using the correct order of operations when solving algebraic expressions.
