Question

2n-5 x 2n-9=16, find n​

Answer 1

Answer:

Step-by-step explanation:

2n-5*2n-9=16

2n-10n-9=16

-8n=25

n=$\frac{-25}{8}$

Answer 2

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

              Given data:- $2n-5\times2n-9=16.$

              To find:- Value of n.

              Solution:-

• Here, we will use the below following steps to find a solution using the transposition method:

• Step 1:- we will Identify the variables and constants in the given simple equation.

• Step 2:-then we Simplify the equation in LHS and RHS.

• Step 3:- Transpose or shift the term on the other side to solve the equation further simplest.

• Step 4:- Simplify the equation using arithmetic operation as required that is mentioned in rule 1 or rule 2 of linear equations.

• Step 5:- Then the result will be the solution for the given linear equation. By using the transposition method. we get,

          $\Rightarrow 2n\times2n-9=16\\\Rightarrow 2 n-10 n-9=16 \\\Rightarrow -8 n-9=16\\\Rightarrow -8n=16+9\\\Rightarrow-8n=25\\\Rightarrow n=-\frac{25}{8} .$

         Hence we will get the value of $n=-\frac{25}{8} .$
