What value could you write in after 3x that would make the equation true for 1. No values of x? 2. All values of x? 3. Just one

Aneli [31]

3x + 8 = 3x + []

Subtract 3x from both sides.

[] = 8

If you want no values of x, it can be any positive value other than 8.
If you want all values of x, the value must be 8.
If you want only one value of x, it is impossible because both equations have the same slope.

Answer:

a = 3
b = -18

Step-by-step explanation:

Using the least common denominator, we have ...

$2-\dfrac{x+1}{x-2}-\dfrac{x-4}{x+2}\\\\=\dfrac{2(x-2)(x+2)-(x+1)(x+2)-(x-4)(x-2)}{(x-2)(x+2)}\\\\=\dfrac{2(x^2-4)-(x^2+3x+2)-(x^2-6x+8)}{x^2-4}\\\\=\dfrac{(2-1-1)x^2+(-3+6)x+(-8-2-8)}{x^2-4}=\boxed{\dfrac{3x-18}{x^2-4}}$

The values of a and b are ...

a = 3

b = -18
