For the following questions, use the system of equations

For the following questions, use the system of equations

3x+2y=14
2x-4y=4

a. Solve the system of equations using either the substitution method or the multiplication/addition method.

b. Check your solution by writing the system as a matrix equation and using the inverse matrix.

c. Verify your solution by graphing the system. Mark the point on your graph that represents the solution.

3x+2y=14
2x-4y=4

6x+4y=28
2x-4y=4
8x = 32
x = 4
2y = 14 - 12 = 2
y = 1
(x , y) = (4 , 1)

Draw the straight lines, they should intersect at (4 , 1) which is the solution of the system.
