Question

PLEASE ANSWER
If a=4 and b= -1 then what is (6a+4b)-(4a+b) ?

Answer 1

Step-by-step explanation:

since a=4

b=-1

(6a+4b)-(4a+b)

=6a+4b-4a-b

=6×4+4×-1-4×4-(-1)

=24-4-16+1

=25-20=5

Answer 2

• As per the data given in the question, we have to find the value of the expression.

           Given data:- $a=4,b=-1.$

           To find:- $(6a+4b)-(4a+b)=?$

           Solution:-

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

• It is the rule used to remember the order of operations to be followed while solving expressions in mathematics.

           where,

              $\begin{array}{l}\mathrm{B}=\text{brackets}\\\mathrm{O}=\text { order of powers or rules } \\\mathrm{D}=\text { division } \\\mathrm{M}=\text { multiplication } \\\mathrm{A}=\text { addition } \\\mathrm{S}=\text { subtraction }\end{array}$

               So that,

         $\begin{array}{l}(6 a+4 b)-(4 a+b) \\=6 a+4 b-4 a-b \\=6 \times 4+4 \times-1-4 \times 4-(-1) \\=24-4-16+1 \\=25-20=5.\end{array}$

        Hence we will get the value $5.$
