Answer:
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 .
