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 equations 4-x = 2x + x 3. part b: make the tables to find the solution to 4 - x = 2 + 3. take the integer values between -3 and 3.part c: how can you solve the equation 4 - x = 2x + 3 graphically
