Answer:

8

Step-by-step explanation:

1) let’s take the original number as “x”

So

3x=28-0.5x

Lol don’t worry I’ll show you how I got that

So it says 3 times a number. That tells me my number, X is multiplied by 3 so I have

3x so far

Next it says “is equal to”, this tells me my number 3x is equal to something so I have this now:

3x=

After that it says “half of a number” so I know I will have 0.5x subtracted from 28. Since it says subtracted from 28 that means my number will be subtracted from 28, not the other way around so

3x=28-0.5X

Now I can solve this by bringing “-0.5” to the left.

3x+0.5x=28

3.5x=28

Divide both sides by 3.5 and

X=8
