Answer:
The equation would be .
Step-by-step explanation:
Given;
Total Number of Video games = 21
Let the number of video game Nicholas has be 'x'.
Now Given:
Robert has 5 fewer games than Nicholas.
so we can say that;
number of video game Robert has =
Also Given:
Charlie has twice as many games as Robert.
so we can say that;
number of video game Charlie has =
we need to write the equation.
Solution:
Now we can say that;
Total Number of Video games is equal to sum of number of video game Nicholas has, number of video game Robert has and number of video game Charlie has.
framing the equation we get;
Hence The equation would be .
On Solving we get;
Adding both side by 15 we get;
Dividing both side by 4 we get;
Hence Nicholas has = 9 video games
Robert has = video games
Charlie has = video games
