John is 3 years younger than twice monica's age. If m represents monica's age, which equation can be used to find j, John's age?

Equation that will be used to find j, John's age is j = 2*m - 3.

Step-by-step explanation:

Let Monica's age be m years and John's age be j years.

Now the condition given to us is that John is 3 years younger than twice Monica's age i. e.;

j = 2*m - 3

We have subtracted 3 from 2*m because john is younger than Monica and his age will be smaller than Monica.

Therefore, equation that can be used to find j, John's age is j = 2*m - 3.
