X=12
This is because you subtract 6 from both sides to get the x isolated.
So x=18-6
x=12 :)
Answer:
The answer is A
Step-by-step explanation:
240,000 = 60%
x = 100%
= 
I think it is number 2, x^2-x+2
Parenthasees
the first onewould evaluate to 4x²
the 2nd one would just be -2x²
The solution of this equation is x = 5 and x = 9.
<h3>What is the solution?</h3>
Let us recall that what we have here is a radical equation as follows;
√7x+1 - √x-5 = 6
When we isolate we have';
√7x+1 = √x-5+6
Taking the square of both sides;
(√7x+1)^2 = (√x-5+6)^2
Hence;
7x+1 = x-5+36+12√x-5
-12√x-5 = -7x-1+x-5+36
12√x-5 = 6x-30
Raising this equation to power 2
144x-720 = 36x^2-360x+900
When we rearrange we obtain;
36x2 - 504x + 1620 = 0
Hence;
x = 5 and x = 9
