Step-by-Step Breakdown of the Equation

Equation:
(19a + 5b + c) − (7a + 3b + c) = 25 − 11

Key Insights

Step 1: Simplify the right-hand side
First, simplify the constant expression on the right:
25 − 11 = 14
So now the equation becomes:
(19a + 5b + c) − (7a + 3b + c) = 14

Step 2: Remove parentheses using the distributive property
When subtracting a parenthetical expression, distribute the negative sign:
= 19a + 5b + c − 7a − 3b − c

Step 3: Combine like terms
Group similar variables and constants:
(19a − 7a) + (5b − 3b) + (c − c)
= 12a + 2b + 0
= 12a + 2b

So now the equation simplifies to:
12a + 2b = 14

Step 4: Interpret the result
The equation has been reduced from involving three variables (a, b, c) to just two (a and b), meaning c cancels out completely—consistent with the original expression’s structure. This confirms the cancellation of c is valid and simplifies the solution pathway.

Final Thoughts

Step 5: Express the final simplified equation
We now have:
12a + 2b = 14
This can be further simplified by dividing through by 2 for a cleaner form:
6a + b = 7

Why This Equation Matters for Students and Learners

This problem exemplifies a powerful algebraic principle: simplifying expressions before solving. By reducing terms and eliminating redundant variables like c, learners:

• Improve their ability to approach complex equations confidently
  
• Develop skills in organizing terms systematically
  
• Enhance algebraic fluency, critical in higher math and STEM fields

Understanding how terms cancel and how coefficients simplify empowers students to tackle similar equations involving multiple variables and operations.
