To solve this problem, create two equations with x and y. The pieces of information that we know are that the first child is 3 times older than the second child. Therefore if we assign child #1 the variable of x and child #2 the variable of y, we could get the following equation:
3x = y
Now, we also know that together their ages equal 50 months. Therefore:
x + y = 50 (months)
So, using these two equations you can use either substitution or elimination to find the values of x and y. You would first need to rearrange the first equation to 3x - y = 0 (just moving the y to the other side).
Then, you could add the equations together as followed:
3x - y = 0
x + y = 50
___________
4x = 50
x = 12.5
And then fill that value in to one of the equations to find y.
3x = y
3(12.5) = y
y = 37.5
So, one child is 12.5 months old and the other is 37.5 months old!

Answer:
Step-by-step explanation:
So in the first carton of orange juice 4 friends shared the juice.
This can be shown as:
The 4 friends got 1/16 of the carton each in the first carton of OJ.
Next for the second carton, it can be shown as:
The 4 friends got 1/32 of the carton each in the first carton of OJ.
Now to see how much they got in total each, we simply add 1/16 to 1/32
Each friend got a total of each from both cartons of OJ.
