To add the two expressions, we can write it as:

4.6x-3 + (-5.3x+9)

We can distribute the plus sign (which means just drop the parenthesis in this case):

4.6x-3-5.3x+9

Now, we can simplify by combining like terms:

-0.7x+6

So you have <span>4.6x − 3 and </span><span>−5.3x + 9. You can only add like terms, which are terms where their variables (and the exponents on the variable) are the same. That means you can add </span>4.6x and −5.3x, and you can also add −3 and 9:
4.6x - 3 + - 5.3x + 9\\&#10;= (4.6x - 5.3x) + (-3 + 9)\\&#10;= -0.7x + 6

-----

Answer: -0.7x + 6
