Y= 2x+6

I posted this question last week no can't really help me but this time I really need your help .
Thank you so much .

Don't forget to show the work .

Answer 1

y = 5x - 9
y = 2x + 6

  5x - 9 = 2x + 6
- 2x       - 2x
  3x - 9 = 6
      + 9 + 9
       3x = 15
        3      3
         x = 5

y = 5x - 9
y = 5(5) - 9
y = 25 - 9
y = 16
(x, y) = (5, 16)
