$2a - 15 \\ \\ when \: a \: = 1 \\ \\ = 2(1) - 15 \\ = 2 - 15\\ = - 13$

Answer 2

Answer:

We will get the value is -13.

Step-by-step explanation:

• We have to evaluate the above expression by using the given data.

        Given data:- a=1

        To find:- Value of 2a-15.

        Solution:-

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

• BODMAS is a order of mathematic operations.

• BODMAS rule is to be followed while solving expressions in mathematics. It stands for,

           B= bracket

           O= order of power or rules

           D= division

           M= multiplication

           A= addition

           S= subtraction

     Now put the value a=1 in the given equation we get,

         $2a-15\\=2(1)-15\\=2-15\\=-13$
