Explanation Given: The system of equation x + y = 2 ; x − y = 4 Solving a system of equation means finding the value of (x, y) which will make both the equation true. There are different types of solution for system of equation. We need to identify the x-intercept and y-intercept of the equation and plot the same to graph the system of equation and conclude the solution based on the below three cases. Case 1: When we get intersecting lines, the solution of system of equations is UNIQUE and it is the point where the graphs intersect. The solution set in interval notation is given by { ( x , y ) } . The solution is described as consistent and independent. Also for intersecting lines, the slope of the system of equations will be DIFFERENT. Case 2: When we get coinciding lines, the solution of system of equations is INFINITE because the lines meet at numerous points. The solution is represented as { x ∈ ℜ , y ∈ ℜ } The solution is described as consistent and dependent. Also for intersecting lines, the slope and y-intercept of the system of equations will be SAME. Case 3: When we have parallel lines, the solution of the system of equations is NO SOLUTION because the lines will never meet. The solution is represented as { } or ∅ . The system of equation hence described as inconsistent. Also for parallel lines, slope is SAME and y-intercept of the equation will be DIFFERENT. Here in this problem, we need to identify the x-intercept and y-intercept of 1 s t and 2 n d equation. X-intercept is the point where the graph cuts the x-axis. To find x-intercept we need to substitute 0 for y and find the respective x value. Y-intercept is the point where the graph cuts the y-axis. To find the y-intercept we need to substitute 0 for x and find the respective y value. The graph of system of equations x + y = 2 and x − y = 4 is given below: Calculation: Description Solving equations x + y = 2 → 1 s t e q u a t i o n x − y = 4 → 2 n d e q u a t i o n Step 1: Identify the x-intercept and y-intercept of 1 s t equationTo find x-intercept we need to substitute 0 for y and find the respective x value
