The sum of two numbers is 37. The larger number is 19 more than the smaller number. What are the numbers?

Step-by-step explanation:

a+b=37

a=19+b

19+b+b=37

19+2b=37

2b=18

b=9

a+9=37

a=28

:the answers are 28 and 9

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
