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