Answer:
math is a difficult subject
A negative times a negative is a positive so...
( - ) ( - ) ( - ) ( -10x ) = -5
10x = -5
x = -5/10
x = -1/2
Answer:
x = 6
Step-by-step explanation:
An inverse variation is
xy = k where k is the constant of variation
8*9 = k
72 = k
xy = k
Let y = 12
x*12 = 72
Divide each side by 12
12x/12 =72/12
x = 6
