The matrix method is being used to solve the system of equations x + 2y = 4 and 3x - y = 6.

if the goal of the first matrix operation is to get a zero in row 2, column 1, then one could
a) subtract 3 from each entry of row 2
b) multiply row 1 by -3 and add the result to row 2
c)divide row 2 by -3 and add to row 1

(05.03 mc) part a: explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x−2 intersect are the solutions of the equation 4x = 2x−2. (4 points) part b: make tables to find the solution to 4x = 2x−2. take the integer values of x between −3 and 3. (4 points) part c: how can you solve the equation 4x = 2x−2 graphically? (2 points)
