Answer:
x=9
Step-by-step explanation:
[tex]\frac{x}{3} +1=4\\pasamos a restar a "1"\\\frac{x}{3} =4-1\\\frac{x}{3} =3\\ahora pasamos a multiplicar a "3"\\x=3*3\\x=9[/tex]
[tex]\bf{\dfrac{x}{3}+1=4 }[/tex]
Multiply both sides of the equation by 3.
- ⇒ x + 3 = 12
Subtract 3 from both sides.
- ⇒ x = 12 - 3
Subtract 3 from 12 to get 9.
- x = 9 ===> Answer
