x = -30
Step-by-step explanation:
x - (-10) = -20
Subtracting a negative is adding
x+10 = -20
Subtract 10 from each side to isolate x
x+10-10 = -20-10
x = -30

For two lines to be perpendicular, their slopes must be negative reciprocals of one another, mathematically:
m1*m2=-1, in this case our reference line has a slope of -3 so:
-3m=-1 divide both sides by -3
m=-1/-3
m=1/3
So the perpendicular line will have a slope of 1/3
