Answer 2

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

            Given data:-$a=-1.$

            To find:- Value of above expression $3a+4.$

            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

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

            $3a+4\\=>3(-1)+4\\=>-3+4\\=>1.$

     Hence we will get the value is $3a+4=1.$
