Answer 2

Answer:

The correct option is 3.

Step-by-step explanation:

The given equation is

$x+7.4=49.8$

We need to solve this equation to find the value of x.

Subtract 7.4 from both the sides.

$x+7.4-7.4=49.8-7.4$

On simplification, we get

$x=42.4$

The value of x is 42.4. So,the solution of the given equation is 42.4.

Therefore the correct option is 3.
