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 :)

please mark as brainliest thank you
Answer: x= -12
Step-by-step explanation:
These are corresponding angles which means they are the same. X+62= 50. Subtract 62 from both sides. X= -12
