Hi I need help. The problems are all two step equations. Please I have to finish it by 10:10 tomorrow, and I have other work to work on and it has to be turned in by 8:00.

A - x=6

B - x=3

C - x=21

D - x=50

E - x=8

F - x=12

G - x=1

H - x=15

I - x=21

J - x=6

K - x=15

L - x=1

M - x=50

N - x=12

O - x=8

P - x=3

Step-by-step explanation:

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
