Answer 1

Answer:

Simplification = 57a + 28

a = 57/28

Step-by-step explanation:

42a + 21a - 6a + 28

-> 57a + 28

-> a = 57/28

Answer 2

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

              Given data:- $42a+21a-6a+28.$

              To find:- Value of above expression.

              Solution:-

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

• BODMAS is an 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

      Therefore, combine terms like together,

            $42a+21a-6a+28\\=63a-6a+28\\=57a+28.$

       Hence we will get the value $57a+28.$
