Question

The sum of three numbers is 15. If the
second number is subtracted from the sum
of first and third numbers then we get 5.
When the third number is subtracted from
the sum of twice the first number and the
second number, we get 4. Find the three
numbers. with the help of determinants​

Answer 1

Answer:Let those three no. Be x,y,z

By 1st condition ,

X+y+z=15

By 2nd condition,

X+z-y=5

By 3rd condition,

2x+y-z=4

By solving this ....

We get ,

D=6

And dx=18

And dy= 30

And dz=42

So, x=dx/d=3

Y=dy/d=5

And z=dz/d=7
