Answer 2

Answer:

=> The correct option is ( a ) 0

Step-by-step explanation:

Given that:-

$8k + 4 = 3 (k - 1 ) + 7$

To find:- The value of the expression:

Here we will use the transposition method.

First of all, we have to identify the variables and the constants.

Then solve the expression of both sides by using various mathematical operations.

As we have,

=> $8k + 4 = 3 (k - 1 ) + 7$

First of all, distribute the terms:

=> $8k + 4 = 3 k - 3 + 7$

Add the numbers:

=> $8k + 4 = 3 k +4$

Now, subtract $4$ from both sides:

=> $8k=3k$

Subtract $3k$ from both sides,

=> $8k-3k=3k-3k$

=> $5k=0$

Divide both sides by $5$, we get

=> $k=0$

Hence, the required solution is 0.
