The sum of two numbers is 109. If four times the smaller number is subtracted from the larger number, the result is 4. What are the two numbers?

Let the numbers be x&y

X+y=109

Taking a as the smallest number we multiply by 4

So according to the question you will have this equation

Y(as the largest number) -4x=4. Y-4x=4

Then find y

Y=4x+4

Substitute y on the first equation to get a

X+y=109

X+4x+4=109

X=21

21+y=109

Y=88

HOPE IT HELPS PLS MARK AS BRAINLIEST

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
