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?
