Question

find four solution of 3x - y = 4​

Answer 1

Answer:

Let x = 0

3(0) - y = 4

0 - y = 4

y = -4

Solution. (0,-4)

Let x = 1

3(1) - y = 4

3 - y = 4

y = 3-4

y = -1

Solution. (1,-1)

Let x = -1

3(-1) - y = 4

-3 - y = 4

-3-4 = y

-7 = y

Solution. (-1,-7)

Let x = 2

3(2) - y = 4

6 - y = 4

y = 6-4

y = 2

Solution. (2,2)

Four Solutions of 3x - y = 4 are (0,-4) ; (1,-1) ; (-1,-7) and (2,2).
