Question

Find the value of x
2(x+7)=13
​

Answer 1

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

              Given data:- $2(x+7)=13.$

              To find:- Value of the expression.

              Solution:-

• Here we will use the transposition method.

• Transposition is one of the linear equations.

• To solve the transposition method we will Identify the variables and constants.

• Then we Simplify the equation in LHS and RHS.

• Now Simplify the equation using arithmetic operations.

        By using the transposition method.

        we get,

                  $2(x+7)=13\\=>2x+14=13\\=>2x=13-14\\=>2x=-1\\=>x=\frac{-1}{2} .$

      Hence we will get the value $x=-\frac{1}{2} .$

Answer 2

As per the data given in the above question.

we have the following details as,

The given equation is 2(x+7)=13

We have to find the value of x from given equation.

Thus, simplifying the given equation we get,

$2(x + 7) = 13 \\ 2x + 14 = 13$

shifting constant one side we get,

$2x = 13 - 14 \\ 2x = - 1 \\ x = \frac{ - 1}{2}$

Hence the value of x is

$\frac{ - 1}{2}$

note:-
