Step-by-step explanation:

we will call the number "X".

So we know that X plus X/2 (i.e., half of X) = 30.

So your equation is:

X+ X/2= 30.

To simplify, multiply both sides by 2 to get rid of the divisor. So you end up with

2x+ x= 60, or 3X=60.

So, divide both sides by 3, and x is 20.

20 + 10 = 30.
