sum of two numbers is 84 .if one Number is 4 less than the other, find the numbers
Answers
Answer:
Y=44 AND X=40
Step-by-step explanation:
X=Y-4
SO, Y-4+Y=84
AND SO Y=44
X=40
If one Number is 4 less than the other, then the numbers are 44 and 40
Solution:
Let the two numbers be "a" and "b"
Given that sum of two numbers is 84
a + b =84 ---- eqn 1
Then also given that one number is 4 less than other
Let us assume "a" be the number which is 4 less than "b"
a = b - 4 ---- eqn 2
Plugging in eqn 2 in eqn 1, we get
b - 4 + b = 84
2b = 88
b = 44
Substitute "b" value in eqn 2, we get
a = 44 - 4 = 40
Hence the two numbers are 40 and 44
