any help would be great plz.

Answer 1

Answer:

x≠{-3,0,-15,3,15}

Step-by-step explanation:

to understand this

you need to know about:

• equation
• PEMDAS

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

• 2×0/15=2/3
• 0/15=2/3
• 0≠2/3

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

• 2×15/15=2/3
• 2≠2/3
