Question

i need help with this problem

Answer 1

2x - 4 = x - 10.

Answer 2

X = negative 6, or -6

Answer 3

well, if you're interested in the work, then here it is:

First, you move like terms to one side, so move "x" by subtracting it from both sides:
\[\large 2x-4 \color{red}{-x} =x-10 \color{red}{-x} \]
\[\large x-4=-10 \]

Now add 4 to each side:
\[\large x-4 \color{blue}{+4} = -10 +\color{blue}{+4} \]

You get:
\[\large x=-6 \]

Answer 4

x=−6
