Answer:
x = -5
Explanation:
You want the solution to the equation 2x -10 = 4x.
Solution
Subtracting 2x from both sides gives ...
-10 = 2x
Dividing both sides by 2 gives ...
-5 = x
The solution is x = -5.

Additional comment
When all of the coefficients have a common factor, sometimes we like to divide the equation by that factor. Here, all of the coefficients are even, so we can start by dividing the equation by 2:
x -5 =2x
Now subtracting x gives the solution:
-5 = x
It still takes 2 steps, so the approach you take will be the one you're most comfortable with.
