Answer 2

Answer:

=> It is verified that, the value of a satisfies the expression.

Step-by-step explanation:

Given that:-

$12a + 4 = 40$ and the value of a is $3$.

We have to verify the expression,

Here we will use the transposition method.

As we have,

=> $12a + 4 = 40$

Now, plug the value of a as $3$:

=> 12 ( 3 ) + 4 = 40

=> 40 = 40

LHS = RHS
