Answer 2

The correct option is 3.

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.
