Answer 2

Answer:

We will get the value of $8a+(-6a)+7a+(-4a)=5a.$

Step-by-step explanation:

• As per the question we have to evaluate the given data.

         Given data:- 8a,-6a.7a,-4a.

         To find:- Sum of 8a,-6a.7a,-4a.

         Solution:-

• To solve the above question we will follow the BODMAS rule.

• BODMAS is an order of mathematic operations.

•  It stands for,

      B= bracket

      O= order of power or rules

      D= division

      M= multiplication

      A= addition

      S=subtraction

       $8a+(-6a)+7a+(-4a)\\=8a-6a+7a+-4a \\=8a-6a+7a-4a \\=2a+7a-4a \\=9a-4a \\=5a\end{array}$
