Question

Solve the following system of equations graphically.

x + y - 4 = 0
x - y = 0

The solution lies in quadrant _____.

Answer 1

x=2

y=2

Ans will1st Quadrant.

Answer 2

Answer:

Step-by-step explanation:

We may add the equations to find the value of the x first,

                                            x + y = 4

                                 +         x - y = 0

The sum would be 2x = 4 which gives the value of x as 2. Substitute this value to any of the equations to solve for y. The value of y is 2. Thus, the solution of the system is (2, 2) which is in the Quadrant 1.
