Answer:
[tex]x = -5[/tex]
Step-by-step explanation:
This is for if you are trying to solve for x. If that is not your goal, do not heed my words.
Subtract 20 from both sides.
[tex]4x + 20 = ?[/tex]
becomes
[tex]4x = -20[/tex]
Divide both sides by 4.
[tex]4x = -20[/tex]
becomes
[tex]x = -5[/tex]
And that's how you'd solve for x.
