Question

12a + 4 = 40 solve this problem​

Answer 1

12a + 4 = 40

=> 12a = 36

=> a = 3

Answer 2

Answer:

=> a = 3

Step-by-step explanation:

Given that:-

$12a + 4 = 40$

To find:- The value of the expression:

Here we will use the transposition method.

We have to follow these steps:-

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

( ii ) Get the variable to one side of the equation. Maintain equation balance while calculating.

( iii ) Then solve the expression of both sides by using various mathematical operations. Simplify both sides.

As we have,

=> $12a + 4 = 40$

Now, subtract both sides by $4$ we get

=> $12a + 4 -4= 40-4$

=> $12a=36$

Divide both sides by $12$, we get

=> $a=3$

Hence, the required solution is 3.
