One number is 4 less than 3 times another if their sum is increased by 5, the result is 25 . The numbers are .
Answers
Step-by-step explanation:
Let the first number be x
Let the second number be y
According to given condition
y= 3x-4
Also given that if sum is increased by 5 then result is 25
So the equation can be written as
x + y +5 = 25
Substituting the value of y we get
x + 3x – 5 + 5 = 25
=> 4x+1 = 25
=> 4x = 24
=> x = 6
Hence first number is 6
Second Number = y= 3 (6) -4 = 14
Answer:
The 2 numbers are 6 and 14.
Step-by-step explanation:
Let the numbers be x and y
=> x + y + 5 = 25
=> x + y = 25 - 5
=> x + y = 20
=> x = 20 - y
Substituting x with 3y - 4
=> 3y - 4 = 20 - y
=> 3y + y = 20 + 4
=> 4y = 24
=> y = 24/4
=> y = 6
=> x + y + 5 = 25
=> x + 6 + 5 = 25
=> x + 11 = 25
=> x = 25 - 11
=> x = 14
Ans- The 2 numbers are 6 and 14.
