Answer:
<h2>x≠{-3,0,-15,3,15}</h2>
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>tips and formulas:</h3>
- to figure out the domain restrictions let's use the given value
<h3>let's solve:</h3>
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
