Question

In 10 years, Mike will be 3 times his current age. What is Mike’s current age?

Answer 1

Answer:

5 years old

5x3 = 15

15 - 5 = 10

Answer 2

Answer:

He is currently 5 years old.

Step-by-step explanation:

Step 1 - You can turn this into an equation:

In 10 years, he will be 3x his current age so:

Let x equal current age:

x + 10 = 3x

Step 2 - Subtract x from both sides:

x + 10 - x = 3x - x

10 = 2x

Step 3 - Divide both sides by 2:

$\frac{10}{2} = \frac{2x}{2}$

5 = x

Hope this helps!
