Answer:

x = 6, PLEASE MARK AS BRAINLIEST

Step-by-step explanation:

Let this number be x:

1) Increase x by 30 = x + 30

2) Divide the result by 2 = [tex]\frac{x+30}{2}[/tex]

3) The number obtained is 3 times the original number =

[tex]\frac{x + 30}{2} = 3x[/tex]

[tex]{x + 30} = 6x[/tex]

[tex]30 = 5x[/tex]

[tex]x = \frac{30}{5}[/tex]

[tex]x = 6[/tex]
