Question

the sum of three no. is 9, if we add twice the second no. in sum of 1st and 3rd we get 7. If we add thrice the 1st no. in the sum of 2nd & 3rd we get -5 find the no.s by using determinant..(Cramer's rule)​

Answer 1

Answer:

Since the other two numbers depend on the first number, let the 1st = x. So the 2nd = 4x and the 3rd = x + 3.

x + 4x + x + 3 = 81

6x + 3 = 81

6x = 78

x = 13

Thus the numbers are 13, 52 and 16.
