Question

The solution of the equation 7n+5 = 12 is​

Answer 1

1

Step-by-step explanation:

7n+5 = 12

7n = 12-5

7n = 7

n = 7/7

n = 1

Answer 2

Answer:

=> The value of n is 1.

Step-by-step explanation:

Given that:-

$7n+5 = 12$

To find:- The value of the expression,

To solve this expression, we have to use the transposition method: 

As we have,

=> $7n+5 = 12$

Now subtract both sides by $5$,

=> $7n+5 -5= 12-5$

=> $7n = 12 -5$

Subtract the numbers,

=> $7n = 7$

Divide both sides by $7$,

=> n = 1

Hence, the required solution is 1.
