What is the solution to the system of equations?

A solution to a system of equations is a set of values for the variable that satisfy all the equations simultaneously. In order to solve a system of equations, one must find all the sets of values of the variables that constitutes solutions of the system.

Step-by-step explanation:

(2,7)

Step-by-step explanation:

n=2p+3

n=5+p

We can combine the equation to a simpler equation

5+p=2p+3 to get p=2p+-2

-p=-2 or p=2

We can plug this in to get n=5+2 to get n=7

2

step-by-step explanation:

1+1=2

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
