Given the following system of linear equations, do Part A and Part B below. (3x = 3-3
y=x+1
• Part A: Using the method of your choice (graphing, substitution or addition), find the solution to the system of linear
equations. Include all of your work in your final answer.
• Part B: In two or more complete sentences, explain why you chose the specific method you used to find the solution
to the system.

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
