Problema Solution
one positive number is 4 times another number. the difference between the two numbers is 123.
Answer provided by our tutors
First, we write equations from the given where 'x' and 'y' are the numbers:
x=4y
x-y=123 (We put 'x-y' rather than 'y-x' because we denoted 'x' as the larger number in 'x=4y' and '123' is positive meaning that the smaller positive number MUST be subtracted from the larger positive number to get a positive answer)
Using Algebrator to solve for 'x' and 'y', we get:
x=164
y=41
