Answer:
Answer is 15 and 20.
Step-by-step explanation:
Let the smaller number be x
and the bigger number be y
1st condition y - x = 5
2nd condition 4x = 3y
x = 3y/4
y - x = 5
y - 3y/4 = 5
y/4 = 5
y = 5 × 4 = 20
therefore, y = 20
y - x = 5
20 - x = 5
-x = - 15
therefore, x = 15
Therefore the smaller number is 15
and the bigger number is 20.
