Answer:
Step-by-step explanation:
Let the greater number be x and the smaller number be y.
So,
<u>Condition # 1:</u>
x - y = 7 --------------(1)
<u>Condition # 2:</u>
3x = 72 --------------(2)
Taking Eq. (2)
3x = 72
Divide both sides by 3
x = 72 / 3
x = 24
Now, Put x = 24 in Eq. (1)
24 - y = 7
Subtract 24 to both sides
-y = 7 - 24
-y = -17
y = 17
Hope this helped!
