Calculating the Sum of 2a + 5a

When it comes to algebraic expressions, adding like terms is a common practice. In this case, we are looking to find the sum of 2a + 5a. To do this, we simply combine the coefficients of the like terms, which are the terms with the same variable.

So, in the expression 2a + 5a, the coefficients of the variable 'a' are 2 and 5. When we add these together, we get:

2a + 5a = 7a

Therefore, the sum of 2a + 5a is 7a. This is because we are adding together 2 'a's and 5 'a's, which gives us a total of 7 'a's.

Understanding how to add like terms is a fundamental concept in algebra and is used in a wide range of mathematical problems. By practicing and mastering this skill, you will be better equipped to solve more complex equations and expressions.

If you would like to learn more about algebraic expressions and how to add like terms, you can visit Khan Academy's Algebra resources for step-by-step tutorials and practice exercises.

Remember, when adding like terms, you are simply combining the coefficients of the same variables. In the case of 2a + 5a, the coefficients are 2 and 5, which when added together give us 7. The variable 'a' remains the same in the final answer, so the sum is 7a.

Practice makes perfect when it comes to algebra, so keep practicing and honing your skills to become more confident in solving mathematical problems involving algebraic expressions.
