The sum of three numbers is 14. The second number
1 answer:
Answer:
4 , 3 and 7
Step-by-step explanation:
Let the numbers be x , y and z
i) The sum of three numbers is 14.
x+y+z=14
ii) The second number is 5 less than twice the first number x.
y=2x-5
iii) The third number is 3 more than the first number x.
z=x+3
Hence
x+y+z=14
x + (2x-5) + (x+3) = 14
x + 2x -5 + x +3 =14
4x-5+3=14
4x-2=14
Adding 2 on both sides
4x=16
Diving whole equation by 4
x=4
Hence the numbers are
4 , 2(4)-5 , 4+3
4,3,7

Answer:
Given:
a + b = 9
=> a = 9 - b
Given:
a x b = 18
=> (9 - b) x b = 18
=> 9b - b^2 = 18
=> b^2 - 9b + 18 = 0
=> (b - 3)(b - 6) = 0
=> b = 3 => a = 6
=> b = 6 => a = 3
