Answer:

Step-by-step explanation:

Let his current age = x

Now if you add 46 to that, you will get x + 46.

x + 46

At which point he will be 3 times as old as he is now

x + 46 = 3x Subtract x from both sides.

x-x + 46 = 3x-x Combine

46 = 2x Divide by 2

46/2=2x/2 Do the division

23 = x

He is 23 right now

===============

It might be a little easier to see if you represent the situation a little more literally.

3x - 46 = x The answer comes to the same thing. You might think about which way you want to do it.
