How do find you equivelant expressions?

You'll have to start off by finding the variables. Ex:

3(x + 3) - 2(x + 3)

As you can see here, the two similar variables are x. By using the distributive property, you will get this:

3x + 9 - 2x + 6

Next, you'll want to subtract the two variables, since 2x has a - in front of it:

1x + 9 + 6

or

x + 9 + 6

Then, you want to add the two numbers without the variable:

x + 15

Your answer is x + 15.
Hopefully that helped! :)

Answer:

See Explanation

Step-by-step explanation:

$A+B= 45 \degree \\ \\ assuming \: \tan \: on \: both \: sides \\ \\\implies \: \tan( A+B)= \tan 45 \degree \\ \\ \implies \: \tan( A+B)= 1 \: \: \\ ( \because \: \tan 45 \degree = 1) \\ \\ \implies \: \frac{\tan \: A +\tan \: B }{1 - \tan \: A .\tan \: B } = 1 \\ \\ \implies \: \tan \: A +\tan \: B = 1 - \tan \: A .\tan \: B \\ \\ \purple{ \implies }\: \orange{ \bold{\tan \: A +\tan \: B + \tan \: A .\tan \: B= 1 }} \\ \\ thus \: proved$
