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:
x = 45 degrees
Step-by-step explanation:
The angles in a triangle adds up to 180 degrees
105 + 30 + x = 180
==>
x = 180-135=45
+x on each side. Then -2 on each side. Then divide both sides by 6 and you have your answer
Answer:
Area = PI * radius ^ 2
Area = PI * 60^2
Area = PI * 3,600
Area = 11,309.73 square miles
