HELP WITH 10 QUESTIONS?!?! HERE IS THE FIRST 1.

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?

A system of equations is shown below.

5x - 5y = 10

3x - 2y = 2
