Answer 1

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 = $\frac{x+30}{2}$

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

$\frac{x + 30}{2} = 3x$

${x + 30} = 6x$

$30 = 5x$

$x = \frac{30}{5}$

$x = 6$
