What values of the variable cannot possibly be solutions for the given equation, without actually solving the equation?
Ne4ueva [31]

Answer:

the solution to the equation is 8.  Any value apart from 8 is not a solution

Step-by-step explanation:

Given the equation

6/3x+2 - 1/x-4 = 0

6/3x+2 = 1/x-4

Cross multiply

6(x-4) = 3x+2

6x - 24 = 3x+2

6x-3x = 2 + 24

3x = 24

x = 24/3

x = 8

Hence the solution to the equation is 8.  Any value apart from 8 is not a solution

Hi there!

Adjacent angles, or angles that are next to each other, add up to 180 degrees. They are supplementary.

Examples: 1 and 4, 3 and 4, 2 and 3, 1 and 1

Opposite angles, or angles that are opposite of each other, have the same measure.

Examples: 1 and 3, 2 and 4

I hope this helps!
