Question

Find the value of the expression 2x +3y +5z when x=2 y=3 and z=5 ​

Answer 1

Here we are given an expression 2x +3y +5z

Values of x, y, and z are given

x = 2, y = 3, and z = 5

We will put these values in the expression

2x +3y +5z = 2( 2 ) + 3( 3 ) + 5( 5 )

                   = 4 + 9 + 25

                  = 38

Hence, the value of 2x +3y +5z will be 38

Answer 2

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

            Given data:- $x=2,y=3,z=5.$

            To find:- Value of the expression $2x+3y+5z=?$

            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,

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

          Therefore,

             $2x+3y+5z\\=2(2)+3(3)+5(5)\\=4+9+25\\=13+25\\=38.$

        Hence we will get the value $38.$
