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:

Step-by-step explanation:
we have the points
(-9,7) and (-6,-3)
step 1
Find the slope
The formula to calculate the slope between two points is equal to
substitute the values


step 2
Find the equation in point slope form

we have


substitute
---> equation in point slope form
step 3
Find the equation of the line in slope intercept form

we have

Isolate the variable y
Distribute right side

subtract 3 both sides
