Y= 2x + 1, hope this helps
Since both equations are equal to y you can just make them equal to each other, like this 3x + 7 = x - 9. From there isolate the varible x on one side so that the solution will be on the other side of the equation. I'll do the steps too for you.
3x + 7 = x - 9
2x + 7 = -9
2x = -16
x = -8
Hope this helps :)

Answer:
a = 7
Step-by-step explanation:
3a - 6 = 8 + a
- Add 6 to both sides (3a = 14 + a)
- Subtract a from both sides (2a = 14)
- Divide both sides by 2 (a = 7)
