Answer:

[tex] \boxed{ \bold{ \boxed{ \sf{2}}}}[/tex]

Step-by-step explanation:

[tex] \sf{4x + 8 = 16}[/tex]

Move 8 to right hand side and change its sign

⇒[tex] \sf{4x = 16 - 8}[/tex]

Subtract 8 from 16

⇒[tex] \sf{4x = 8}[/tex]

Divide both sides of the equation by 4

⇒[tex] \sf{ \frac{4x}{4} = \frac{8}{4} }[/tex]

Calculate

⇒[tex] \sf{x = 2}[/tex]

Hope I helped!

Best regards!!
