Solving the Question

We're given:

  • 3x-y=-6
  • Find 4 solutions

We can start by isolating one of the variables, like y:


3x-y=-6\\-y=-3x-6\\y=3x+6

Now we can find four solutions by plugging in any number for x:


y=3x+6\\y=3(1)+6\\y=3+6\\y=9

First solution: (1,9)


y=3x+6\\y=3(2)+6\\y=6+6\\y=12

Second solution: (2,12)


y=3x+6\\y=3(3)+6\\y=9+6\\y=15

Third solution: (3,15)


y=3x+6\\y=3(4)+6\\y=12+6\\y=18

Fourth solution: (4,18)

Possible Answers

First solution: (1,9)

Second solution: (2,12)

Third solution: (3,15)

Fourth solution: (4,18)
