Solving the Equation: (7a + 3) + (-a - 5) = -16
This article will guide you through the steps of solving the equation (7a + 3) + (-a - 5) = -16.
Understanding the Equation
The equation involves combining like terms and solving for the variable 'a'. Let's break it down:
- (7a + 3) + (-a - 5): This part represents the sum of two expressions.
- -16: This is the result of the sum.
Solving the Equation
-
Combine like terms:
- 7a - a = 6a
- 3 - 5 = -2
- Therefore, the simplified equation becomes: 6a - 2 = -16
-
Isolate the variable term:
- Add 2 to both sides of the equation: 6a = -14
-
Solve for 'a':
- Divide both sides by 6: a = -14/6
-
Simplify the solution:
- a = -7/3
Conclusion
Therefore, the solution to the equation (7a + 3) + (-a - 5) = -16 is a = -7/3.
By following these steps, you can effectively solve similar equations involving combining like terms and isolating the variable.
