Sally was asked to find two integers such that one is three less than 4 times the other and the sum of the two integers is 42. the integers must be

X + y = 42 ...(sum of 2 integers is 42)
x = 4y - 3...(one is 3 less then 4 times the other)

4y - 3 + y = 42
5y = 45
y = 45/5
y = 9

x = 4y - 3
x = 4(9) - 3
x = 36 - 3
x = 33

the integers are : 33 and 9

5would be the answer- explanation
