Which ordered pair is a solution of the system of equations? y= 3x-1 and y= 5x + 1

x = -1

Step-by-step explanation:

y = 3x - 1

y = 5x + 1

We can set these equations equal to each other, since they are both y.

3x - 1 = 5x + 1

-3x        -3x

-1 = 2x + 1

-1          - 1

-2 = 2x

Divide by 2 on both sides.

x = -1

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
