Question

find four solutions for the equation 2x-y=3

Answer 1

Answer:

(0,-3) (1.5,0) (2,1) (1,-1)

Step-by-step explanation:

2x-y=3

x=0, y = -3   => (0,-3)

y=0, x = 3/2 = 1.5 => (1.5,0)

y=1, 2x - 1 = 3

2x -1 = 3

2x     = 3+1

2x     = 4

x       = 4/2 = 2 => (2,1)

x=1, 2(1) -1 = 3

          -y = 3-2

          -y = 1

           y = -1 => (1,-1)
