Answer:
x≠{-3,0,-15,3,15}
Explanation:
to understand this
you need to know about:
tips and formulas:
- to figure out the domain restrictions let's use the given value
let's solve:
let's check the equality by using x=-3
- 2×-3/15 = 2/3
- -6/15=2/3
- -3/5≠2/3
let's check the equality by using x=0
let's check the equality by using x=-15
- 2×-15/15=2/3
- 2×-1=2/3
- -2≠2/3
let's check the equality by using x=3
- 2×3/15=2/3
- 6/15≠2/3
- 3/5≠2/3
let's check the equality by using x=15
