Mike is 19.

If you turn the question into an equation it turns to:
J x 2 - 3 = M

So since you don’t know Jasmine’s age you would use guess and check. 8,9, and 10 didn’t work but when you put in 11:
11 x 2 - 3 = M
22 - 3 = M
19 = M

And to check your work
J + M has to equal 30 so,
11 + 19 = 30
30 = 30

Mike's age is 19 years.

Two equations can be derived from this question:

j + m = 30 equation 1

2j - m = 3 equation 2

Where:

j = Jasmine's age

m = Mike's age

To determine Mike's age, take the following steps:

  • Multiply equation 1 by 2

2j + 2m = 60 equation 3

  • Subtract equation 2 from 3

3m = 57

  • Divide both sides by 3

m = 19 years
