4 Use the system of equations shown. 3x + 4y = -9
9x + 2y = 3
a. Would you choose substitution or elimination to solve this system? Explain.
b. Solve the system using the method you chose in problem 4a. Show your work.

(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)
