Answer:
X= -8
Step-by-step explanation:
There are a few ways to go about this, my answer would be to make a proportion:
Take the original equation and rewrite as
396/x-10 = -22/1
Take the diagonals and multiply setting them equal to each other
396 = -22(x-10)
Simplify if possible
396= -22x +220
Subtract 220 to both sides
176= -22x
Divide by -22
x= -8
