One number is 4 less than 3 times another number. if their sum is 16, find the numbers.
what equations could be used to solve the problem if x represents a number?

One number is 11 and another is 5

Step-by-step explanation:

One number is 4 less than 3 times another number:

If we let "one number" be x, and

"another number" be y, we can write:

If their sum is 16:

This means if we add both the numbers, x & y, we get 16:

Now substituting equation 1 into equation 2, we can solve for y:

Now substituting y=5 into equation 1, we can solve for x:

Hence one number is 11 and another is 5
