The sum of thrice the first number, second number and twice the third number is 5. If thrice the second number is subtracted from the sum of first number and, thrice the third we get 2. If the third numbers is subtracted from the sum of twice the first, thrice the second, we get 1. Fidn the numbers.s

If three numbers are added the sum is 15. If the second number is subtracted from the sum of first and third number then we get 5 and if twice the first number is added to the second and the third number is subtracted from the sum we get 4 . Use matrices to find the numbers.
