To find sum of three numbers 14,27 and 13, we can have two ways:(a) We may first add 14 and 27 to get 41 and then add 13 to it to get the total sum 54 (b) or we may add 27 and 13 to get 40 and then add 14 to get the sum 54

To find sum of three numbers 14,27 and 13, we can have two ways : we may first add 14 and 27 to get 41 and then add 13 to it to get the total sum 54 (b) or We may add 27 and 13 to get 40 and then add 14 to get the sum 54. Thus, (14+27)+13 = 14+(27+13)

The sum of three numbers is 6. If we multiply third number by 3 and add second number to it, we get 11. By adding first and third number, we get double of the second number. Represent it algebraically and find the numbers using matrix method.
