Answer:


\boxed{ \bold{ \huge{ \boxed{ \sf{x = 4}}}}}

Explanation:


\sf{2x + 4 = 12}

Move 4 to right hand side and change it's sign


\dashrightarrow{ \sf{2x = 12 - 4}}

Subtract 4 from 12


\dashrightarrow{ \sf{2x = 8}}

Divide both sides by 2


\dashrightarrow{ \sf{ (2x)/(2) = (8)/(2) }}

Calculate


\dashrightarrow{\sf{x = 4}}

Hope I helped!

Best regards! :D

Answer:


x=4

Explanation:


2x+4=12

To solve this equation, first we must minus out(subtract) 4 from both sides of the equation.


2x+4-4=12-4

This equals
2x=8

Now we will make this into a fraction and divide the sides by 2.


(2x)/(2) equals to
(8)/(2)

Now we got an answer!


x=4

Hope this helps!
