Question

Answer 1

Do you have an idea on how to start using my previous post as a guide?

Answer 2

Answer 3

no i don't

Answer 4

Hm, k, start by subtracting 9 from both sides

Answer 5

ok i know what the x value is. i just don't know how to find if it's extraneous or not

Answer 6

Ok extraneous basically means it doesn't work for the equation, like if you after plug in and simplify and it gives you something like 11 = 25 then it doesn't work.

So what's the x value you have?

Answer 7

the x value i have is 104

Answer 8

K, so plug in 104 for x,

√(104-95)+9=6

√(9) + 9 = 6

What is the square root of 9? (simple) >.>

Answer 9

i got that too. so now i know that it's extraneous thank you..

Answer 10

Yw,

3 + 9 = 6

12 = 6 therefore it doesn't work :D

Gl!
