Answer:
<u>The correct answer is B. {-2,4}</u>
Step-by-step explanation:
Let's solve for x, this way:
x + 4/4 = x /x -2
(x + 4) * ((x - 2) = 4 * x
x² - 2x + 4x -8 = 4x
x² - 2x + 4x -8 - 4x = 0
x² - 2x -8 = 0
(x - 4) * (x +2) = 0
x - 4 = 0
x + 2 = 0
x₁ = 4
x₂ = - 2
<u>The correct answer is B. {-2,4}</u>

Sadly, the answer to your question is 'No'. The work written under
the problem on the paper is not correct ... because you tried to do
too much !
You can't combine 'm' terms with 'n' terms or with plain numbers.
They all need to stay separate all the way to the end.
So, actually, your first written line is the answer . . . <em>7m - 35 + 3n</em>
That's as far as you can go. You can't combine these terms. Stop there !
