Question

Solve the following
1) 8(k + 7) = 6 x 5 ​

Answer 1

As context to question asked,

We have to determine the value of k in the given expression  $8(k+7)=6\times 5$

For determining the value of "k" we will separate the like terms at one side, i.e. we will kept the terms containing "k" at one side and other constant at other side.

So, we will get,

$8(k+7)=6\times 5\\8k+56 = 30\\=>8k = 30-56\\=>8k = -26\\=>k = -\frac{26}{8} = -\frac{13}{4}$

Hence, value of "k" for the given expression will be $-\frac{13}{4}$.

Answer 2

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

      Given data:-$8(k+7)=6\times5.$

      To find:- value of the expression.

     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,

        $\Rightarrow 8(k+7)=6\times5\\\Rightarrow 8k+56=30\\\Rightarrow 8k=30-56\\\Rightarrow k=\frac{-26}{8}=\frac{-13}{4}.$

 Hence, the value will be $\frac{-13}{4}.$
