Question

In the equation 7k – 7 = 7, the variable is _______.

Answer 1

Answer:

7k-3=25

7k=25+3

7k=28

k=28/7

k=4

Answer 2

Answer:

=> k = 2

Step-by-step explanation:

Given that:-

$7k -7 = 7$

As we have to find the value of the equation,

For simplifying this expression we have to use the transposition method:

We have,

=> $7k -7 = 7$

Now, add both sides by $7$:

=> $7k -7+7 = 7+7$

By simplifying it further, we get

=> $7k = 7 + 7$

Add the numbers, we get

=> $7k = 14$

Divide both sides by $7$:

=> $k = 2$

Hence, the required solution is 2.
