Answer:

And we can subtract 4x in both sides and we got:

Now we can subtract in both sides 16 and we got:

And if we divide both sides by 4 we got:

And the best solution would be:
-7
Step-by-step explanation:
For this case we assume the following equation:

And we can subtract 4x in both sides and we got:

Now we can subtract in both sides 16 and we got:

And if we divide both sides by 4 we got:

And the best solution would be:
