Answer:
N - 4 = 3(M - 4). Simplified further, N - 4 = 3(M - 4)
Step-by-step explanation:
Given,
Nina is N years old now and;
Maryna is M years old now
If four years ago, Nina was three times as old as Maryna was, then
Four years ago, Nina's age was N - 4
Four years ago, Maryna's age was M - 4
Given that Nina was three times as old as Maryna was four years ago, it means that
N - 4 = 3(M - 4)
To solve further
N = 3m - 12 + 4
N = 3M - 8
Answer:
The main difference is that one has the equal sign before it while the other has it after.
You can decide which one to use based on each individual expression. If you are still simplifying, put it like this: ()=. If you are done simplifying and have your answer and are using a parenthesis, put it like this: =()
